Definitions
- the present invention relates to a copper-based sintered alloy, and more specifically to a Pb-free copper alloy sliding material having excellent sliding characteristics without containing Pb.
- Pb which is normally added to sliding copper alloys, expands and expands on the sliding surface due to temperature rise during sliding. As a result, Pb cools the sliding surface and at the same time has an excellent self-lubricating action. To prevent seizure. Furthermore, since Pb is a soft dispersed phase, it has excellent compatibility and foreign substance embedment. Although it has such excellent properties, Pb is easily corroded by acids other than sulfuric acid and is a harmful substance. Therefore, Cu-Bi sintered sintered gold for sliding materials in which Pb is substituted with Bi has been developed. . The Cu-Bi sintered alloy has a structure in which the copper matrix and Bi are separated, and the Bi phase present on the sliding surface is effective for seizure resistance.
- Japanese Patent No. 3421724 which is one of them, 0.5 to 15% by weight of Sn,! To 20% by weight of Bi, 0 .;! To 10% by volume, It has a composition of hard particles selected from borides, kaides, oxides, nitrides, carbides, intermetallic compounds, the balance Cu, and the hard particles have an average particle size of 1 to 45 m, copper It is mixed in the Bi phase dispersed in the matrix.
- Bi acts as a cushion to mitigate the property of hard particles exposed on the surface of Matritus attacking the mating material.
- B ⁇ has the property of embedding hard particles that have fallen off.
- each one of the hard particles falls on the sliding surface and is completely enclosed in the Bi phase! /, The force, or part of it is enclosed in the Bi phase and the rest is copper. Bonded with matrix.
- Patent Document 2 filed by the present applicant, which is another conventional example: Japanese Patent Application Laid-Open No. 2005-200703, the mass% is 1 to 15% (Sn ,;! To 15% Bi, 0 . ⁇ ! Containing hard particles with an average particle size of 10 to 50 111 and hard particles with a hard contact ratio of the Bi phase with respect to the entire circumference of the hard particles with respect to the Bi phase in contact with the hard particles Sintered copper alloys with a particle content ratio of 70% or more have been proposed, and when the hard particle contact ratio is 50%, one hard The particles are 50% in contact with the Bi phase, and the remaining 50% are in contact with the copper matrix. This ratio is referred to as “hard material contact ratio” in Patent Document 2.
- Patent Document 2 since the hard material contact ratio is 50% or less, the length in contact with the copper matrix is longer than the length in contact with the Bi phase. In Patent Document 2, such hard particles are 70% or more of the total number of particles. In Patent Document 2, this ratio is referred to as the “hard substance presence ratio”, and a maximum of 94% is achieved. The remaining 6% of this 94% has a hard contact rate of 50-; 100%, in which case the hard particles are completely enclosed within the Bi phase.
- Patent Document 2 when focusing on individual hard particles, the hard particles are taken up by half or less in length into the Bi phase, and when focusing on the entire hard particles, the Bi phase is as much as possible. The tissue is adjusted so that it does not touch the surface. For such structure control, short-time sintering by high-frequency sintering is employed.
- Patent Document 1 Japanese Patent No. 3421724
- Patent Document 2 Japanese Patent Laid-Open No. 2005-200703
- an object of the present invention is to provide a Cu—Sn—Bi—hard particle-based sliding material capable of preventing a seizure resistance deterioration with time.
- the Pb-free copper alloy sliding material according to the present invention has a mass% of 1 to 15% (Sn ,;! To 15% Bi, and! To 10% average particle size of 5 to 70 m.
- Sn ,;! To 15% Bi, and! To 10% average particle size of 5 to 70 m.
- the balance consisting of Cu and inevitable impurities, with the Bi phase and hard particles dispersed in the copper matrix, all of the hard particles are bonded to the copper matrix. It is characterized by that.
- the present invention will be described in detail below.
- Sn is an element that strengthens the matrix, raises the recrystallization temperature, and affects the sintered structure. If the Sn content is less than 1% by mass, the recrystallization temperature of the copper alloy becomes too low, and (3) Bi preferentially covers the copper alloy powder surface, as explained in the paragraph of the sintering method. The hard particles and the copper matrix are joined. On the other hand, if the Sn content is 15% by mass or more, a Cu-Sn intermetallic compound is formed, so that the copper alloy matrix becomes brittle and seizure resistance at the initial stage of sliding decreases.
- the preferred Sn content is 2 to 10% by mass, more preferably 2 to 6% by mass.
- Bi is an element that exhibits the same effect as Pb of the conventional material, and improves the conformability and seizure resistance. Furthermore, Bi generates the liquid phase necessary for liquid phase sintering. If the Bi content is less than 1% by mass, the Bi surface exposure will be low from the beginning of sliding! /, And seizure resistance will be low at the beginning of sliding. Also, if the Bi content is 15% by mass or more, the hard particles are easily brought into contact with Bi, so that the hard particles are retained, so that the Cu matrix cannot be prevented from flowing and seizure resistance is lowered.
- the Bi content is preferably 2 to 10% by mass, more preferably 3 to 8% by mass.
- Hard particles increase the wear resistance and prevent Cu matrix flow. When the hard particle content is less than 1% by mass, these effects are insufficient and seizure resistance is lowered. On the other hand, if the content of hard particles is 10% by mass or more, metal fatigue tends to occur starting from the interface between the hard particles and the copper matrix, and seizure resistance is reduced.
- Hard particles include Fe-P compounds such as Fe P and Fe P, phosphides such as Ni P, Ni
- Carbides Al C, SiC, WC, Fe C, Mo C, Mn C and other carbides, Ni—Sn based, Fe—
- Intermetallic compounds such as W, Fe-Mo, Fe-Mn, Cr-Al, V-Al, Ti-Al, W-Al, Si-Mn, Ni-based self-fluxing alloys, Co Force that can use a self-fluxing alloy, etc.
- Fe P, F that is easy to cause diffusion bonding with the copper matrix during sintering and has the appropriate hardness
- Fe—P compounds such as 3 e P.
- the average particle size of the hard particles is less than 5 m, the copper matrix has a small anti-flow effect. And seizure resistance is reduced over time.
- the average particle size of the hard particles is 70 ⁇ or more, the probability that the hard particles and the Bi phase are present at the same position increases, so that it becomes difficult for the hard particles to join the copper matrix, and seizure resistance over time. Becomes lower.
- the average particle size of the preferred hard particles is. -50 m, more preferably 15-40 m 111.
- P can be added to the copper matrix component.
- the effect of P is to improve the sinterability of copper matrix and at the same time improve the adhesion to the back metal. If the P content is less than 0.02% by mass, the effect is small. If it exceeds 0.2% by mass, the copper matrix becomes too hard and the seizure resistance decreases, and at the same time the adhesion to the back metal decreases. Do
- Components other than the above are impurities, and in particular, Pb is allowed only at the impurity level.
- the basic structural constituent phases of the Cu—Sn—Bi—hard particle sintered material of the present invention are copper matrix, Bi phase, and hard particles, and the Bi phase and the hard particles are present at the boundaries of the particles constituting the copper matrix. It is the same as the structure of the conventional material shown in Patent Documents 1 and 2 in that it exists.
- the structural feature of the present invention is that all hard particles are joined to the copper matrix on the sliding surface. In this regard, if the hard particles are phosphides that are easy to interdiffuse with the copper matrix, interdiffusion occurs between P in the hard material and Cu in the matrix, and bonding is performed without the Bi phase. The bonding strength between the hard particles and the copper matrix is increased. Furthermore, as the sintering method, it is carried out in Patent Document 2! /, And electric resistance heating furnace sintering is preferred over high frequency induction heating sintering.
- the bonding force between the hard particles and the Bi phase is due to “shape bonding” due to the anchor effect, while the bonding between the phosphide-based hard particles and the copper matrix is equivalent to “diffusion bonding” with mutual diffusion. And strong. Therefore, the copper matrix becomes difficult to flow due to the latter bonding force. Furthermore, even if the temperature rises on the sliding surface and the Bi phase softens, the copper matrix is bonded to the hard particles and the hard particles are not softened at all, so that the copper matrix flows near the hard particles. Absent.
- all the hard particles of the sintered material can be bonded to the copper matrix.
- the sliding surface and the planned sliding surface that is, the wear depth that occurs during the life of the sliding member is known, for example, if the AT bush has a planned wear depth of about 10 to 80 m, It is sufficient that a predetermined bonding state is obtained for this depth.
- Fe—P compound hard particles and Cu—Sn—Bi alloy are sintered.
- the raw material of the powder includes atomized powder.
- Patent Document 1 The structure control method of Patent Document 1 is a mixture of hard particles and Bi phase. Fe-P compounds are not used as hard particles. Also, some of the hard particles are in contact with only the Bi phase and are bonded to the copper matrix!
- the P deoxidizes the Cu-Sn-Bi alloy powder surface. Then, by increasing the activation degree of the powder surface, the bonding between the Fe—P compound and the copper matrix proceeds.
- This deoxidation and joining of hard particles are more likely to occur when the temperature rise gradient during the temperature rise during sintering is smaller.
- a temperature increase gradient of 300 to 1000 ° C / min in the temperature range of room temperature to 600 ° C is preferable. If this temperature rise gradient is too low, the deoxidation effect due to P will disappear during the temperature rise, while if it is too high, Bi will collect from the Cu-Sn-Bi powder around the Fe-P compound particles. This concentration occurs before the powder surface activity increases.
- a preliminary alloy of Cu—Sn—Bi alloy was prepared so as to have the composition shown in Table 1, and the particle size of the powder was reduced to 150 m or less by the atomization method.
- 11-31-81 alloy powder and hard particles shown in Table 1 were mixed under normal conditions using a V-type blender, and the mixed powder was lmm on a steel plate with a width of 150 mm and a length of 2000 mm.
- the sintering conditions were set to 600 ° C / min in the temperature range from room temperature to 600 ° C, the sintering temperature was 700 to 900 ° C, and the sintering time was 5 to 30 minutes. After that, the sintered layer was densified by rolling, and secondary sintering was performed again under the same conditions.
- Comparative Example 1 does not contain Bi, seizure resistance after initial and steady sliding is poor. Since Comparative Example 2 has a high Bi content, it still has poor seizure resistance after initial and steady sliding. Since Comparative Example 3 has a low Sn content, the initial seizure resistance is good, but the seizure resistance after steady sliding is poor. Since Comparative Example 4 has a high Sn content, it has poor seizure resistance after initial and steady sliding. Comparative Example 5 has good initial seizure resistance because the hard material is Al 2 O The seizure resistance after steady sliding is poor. Since Comparative Example 6 does not contain hard particles, the initial seizure resistance is good, but the seizure resistance after steady sliding is poor.
- Comparative Example 7 since the amount of hard particles added is large, the initial seizure resistance is good. The seizure resistance after steady sliding is poor. In Comparative Example 8, since the average particle size of the hard particles is large, the initial seizure resistance is good, but the seizure resistance after steady sliding is poor. In Comparative Example 9, since the average particle size of the hard material is small, the initial seizure resistance is good, but the seizure resistance after steady sliding is poor.
- the tissue observation is as follows. In the above-mentioned parts of the sintered material that can be applied to actual products, observations in the range of lOmm x 10 mm were made at three locations. Magnification the surface area field of view is 0. 50 mm 2 is in order to observe at 100 times optical microscope is required 600 times measurement. First, as a preliminary test, No. 1 and No. 22 in Table 1 were subjected to the above-mentioned 600 times of microscopic observation with an OLYMPUS PC control microscope, and in each case, all hard particles were observed on the copper matrix and sliding surface. It was confirmed that they were joined.
- FIGS. 1, 2, and 3 show micrographs of the polished surfaces of the test pieces of Nos. 5, 9, and 21 of Examples of the present application, respectively. From these, it can be seen that the hard particles are bonded to the copper matrix. These photomicrographs are shown in Patent Document 2 (10% Bi— 2% Fe P
- Comparative Example 2 the hard particles were completely surrounded by the Bi phase as shown in FIG.
- Comparative Example 3 some of the hard particles with low recrystallization temperature due to the low Sn content were completely surrounded by the Bi phase.
- Example 2 when P was added to a part of the composition of Example 1 in Table 1 and the same test was performed on the test piece prepared by the same method as in Table 1, an appropriate amount of P was added.
- the initial seizure surface pressure and the steady seizure surface pressure after sliding in Example 2 were even better than Example 1 in Table 1 where P was not added. This is because by adding P, sintering progressed further, diffusion bonding between the copper matrix and the hard material progressed, and the hard material was better retained.
- the sliding material of the present invention exhibits stable performance because of little deterioration in seizure resistance due to sliding. Accordingly, the material of the present invention can be force s to provide automatic trans honey Chillon (AT) bush, piston pin bushing, as general machinery bush a reliable component.
- AT automatic trans honey Chillon
