A method in which a treatment material is supplied in the form of powder, liquid, gas, etc., and heated to cause it to diffuse and permeate to form a surface layer (7-mentation method).

母材の変形や術撃値の低下等が起こる為実用的でなく、
温度の制限があり、結局処理時間を短縮できながった。Among these, the surface treatments in the cementation method include carburizing, nitriding, diffusion plating, etc., and the treatment Pt (material is diffused and infiltrated into the base material surface 1ra to form an alloy layer and an intermetallic compound layer). However, its diffusion rate was extremely slow and the surface treatment required an extremely long time.For example, taking carburization, which is a typical cementation process, the first
As shown in the figure, it took about 4 hours to obtain one carburized layer by heating at 9()0°C. Table 10 In order to shorten the processing time, it is possible to increase the temperature, but raising the base material temperature too much will cause deformation of the base material and decrease in the attack value, so it is not practical.
Due to temperature limitations, it was not possible to shorten the processing time.

拡９５１１組織や、複雑に入り組んだ混合組織（以下１

It is necessary to have a strong connection with the The adhesion of the treated material to the fourth metal is achieved through mechanical adhesion, in which the treated material is deeply engaged with a rough anchor pattern applied to the surface of the base metal, such as by thermal spraying, but in order to strengthen the adhesion, it is necessary to Reactive knitted fibers,

Therefore, it works to prevent peeling and cracking of the joint surface.

However, in the conventional methods mentioned above (vapor phase, melting, electroplating, thermal spraying, etc.), the expansion If' between the material and the treated material (to promote tissue penetration, the base material is heated to a high temperature for a long time). Although it is effective to heat the material for a certain period of time, this has a large thermal effect on the base material, causing deformation, distortion, and structural changes, which has been a major limitation.

供することを目的とする。The present invention aims to solve the problems of the prior art described above, and when performing surface treatment in which a treatment material is diffused and penetrated into the surface to be treated, it is possible to perform surface treatment in an extremely short time. In addition, when performing surface treatment to form a coating of treated material on the surface to be treated, it is possible to reliably form a thick and uniform diffusion layer, reaction layer, or mixed structure layer between the coating and the base material, allowing for close contact. It is an object of the present invention to provide a surface treatment method capable of obtaining a surface treated body with excellent strength.
上記目的を達成すべくなされた本発明の表面処理方法は

させながら、所定の表面処理を行うことを特徴とする。The surface treatment method of the present invention, which has been made to achieve the above object, is characterized by performing a predetermined surface treatment on the extreme surface layer of the surface to be treated of the base material in a molten state or while being molten.

ずつ溶融し、溶融位置を移動させればよい。In either case, the thickness of the extreme surface layer in the molten state should be the minimum depth necessary to form a diffusion structure of the desired thickness, in order to minimize the thermal effect on the base material body. It is desirable that the very surface layer of the surface to be treated be kept in a molten state for a very short time, which is generally less than 1 hour. The timing of heating and melting the extreme surface layer can be selected as appropriate depending on the treatment method, such as before or after supplying the treatment material to the surface to be treated, or while supplying the treatment material, but at least when the treatment material is in contact with the surface to be treated. Therefore, it is necessary to bring the treatment material into contact with the surface to be treated while the extreme surface layer of the surface to be treated is in a molten state or while the extreme surface layer is in a molten state. However, it is not necessary to melt the extreme surface layer over the entire surface to be processed at the same time, and it is sufficient to melt small areas at a time and move the melting position.

い。For example, when applying the present invention to cementition,
It is sufficient to keep the treatment material in contact with the entire surface to be treated and melt the surface one by one in small areas. Also, when applying the present invention to thermal spraying, heat and melt an area slightly wider than the thermal spraying area, and then What is necessary is just to move a heating part following the movement of a part.

給した状態で処理材の上から被処理面の極表面層を加熱
溶融できること等の利点を有しているので好適である。As a heating method for melting the extreme surface layer of the surface to be treated, induction heating using high frequency waves, plasma jet, arc, electron beam, laser beam, or heating using a parner may be used alone or in combination. It may be selected as appropriate depending on the type of processing. Among these, induction heating using high frequency can heat a relatively wide area at the same time, the heating depth can be adjusted by adjusting the frequency, the heating amount can be adjusted by adjusting the current, and the treatment can be performed while the treatment material is supplied to the surface to be treated. This method is suitable because it has the advantage of being able to heat and melt the extreme surface layer of the surface to be treated from above the material.

の極表面層を溶融状態としてもよい。Further, in order to facilitate melting of the extreme surface layer, the base material may be preheated as appropriate. The treatment material supplied to the surface to be treated may be preheated. Note that the surface to be processed does not necessarily need to be melted only by an external heat source, and may be melted by heat from the outside and heat of a processing material supplied to the surface to be processed. For example, in the case of thermal spraying, the surface to be treated is heated with an external heat source close to its melting point, and then the heated surface is sprayed with a thermal spray material molten at a high temperature. The surface layer may be in a molten state.
表面処理を行う雰囲気は、特に限定されず、大気中であ

対しても施行が容易に行える等の効果も有している。As described above, the present invention treats the extreme surface layer of the surface to be treated in a molten state or while being molten, so when surface treatment is performed by diffusion and osmosis, the rate of diffusion and osmosis is extremely fast. , a surface-treated body with a good diffusion structure can be obtained in a short time, and when forming a coating of the treated material, the coating is bonded to the molten surface layer, so that the coating and the matrix are bonded. This has the excellent effect of producing a surface-treated body with strong adhesion in which a thick diffusion layer and mixed structure are formed between the material and the material. In addition, since the heating is limited to only the extreme surface layer, there is no deformation of the base material, and there is no change in structure.
An extremely precise surface treatment can be obtained. Furthermore,
Work efficiency is good because heating time is short, and heating can be done by heating only the extreme surface layer, so there is no need for a heating furnace, and it also has the advantage of being easy to apply even to large objects.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.
