Abstract
The invention discloses a method for electrodeposition of a solid lubricating film by a molybdenum disulfide liquid lubricant. The method consists of: first cleaning a part, putting the part in a molybdenum disulfide liquid lubricant, conducting electrodeposition for 1-5min under a voltage of 50-90V and a temperature of 26-30DEG C, then taking the part out, cleaning and draining it, and curing the part for 20-40min at 170-180DEG C, thus obtaining a molybdenum disulfide solid lubricating film formed on the part. Compared with current methods that always rely on the traditional mode of spraying a solid lubricating film to satisfy lubrication performance need, the method provided in the invention makes the lubricating film with good uniformity and binding force. The film can be assembled and disassembled repeatedly without being damaged, can work under high and low temperature environments, has the property of special medium (red oil) resistance, and guarantees the lubrication property, resistance to corrosion, seizure and the like of the lubricating part, thus being able to be applied to lubrication of various high precision bearings in the fields of aviation, aerospace, and ships etc., and also being applicable to solid lubrication of parts in other fields.
Description
Technical field
The present invention relates to the solid-film lubrication technical field, particularly relate to a kind of method of solid lubricant film with molybdenumdisulphide liquid lubricant electricity.
Background technology
The solid-film lubrication technology just obtains development after World War II, the states such as the U.S., USSR (Union of Soviet Socialist Republics) are applied to lubrication technology in the fields such as aircraft engine, aircraft, space satellite, guided missile, space ship, have obtained good application and popularization.And the research of China's solid-film lubrication technology starts from phase later 1950s, early sixties, and solid lubricant has obtained comparatively satisfied effect in some national defence, military project unit.There has been larger development in China over nearly 40 years aspect solid lubricant.Relevant research work is very active, and has solved the problem in some national defence tips and the development of the national economy.Successively develop over one hundred kind of solid lubricant, created various types of evaluation methods, experimental installation.But the achievement in past biases toward experience, imitation and application more, the exploration work of fundamental research and novel solid lubricant structure and test design method is few, the solid lubricant quality that oneself has is stable not enough, kind be far from stdn, seriation, compare with international most advanced level, also exist gap.
It is that solid matter is coated on frictional interface that solid lubrication is processed, and rubs, reduces wear, improves supporting capacity to reduce, prolongs friction durability, and product is applied one deck lubricant film layer.Particularly the axle of some in Investment in fastener industry, nut class (self-locking class nut, plate nut) and bolt class need repeatedly repeated disassembled and assembled, so the quality of lubricant film layer is most important.Traditional solid lubricant film is varied, such as graphite, tetrafluoroethylene, molybdenumdisulphide lubricant film etc., but use more still molybdenumdisulphide lubricant film lubricant, and the coating method of solid lubricant film mostly is dip-coating, spraying, brushing, but the bonding force of the lubricant film that these coating methods form is bad, aesthetic appearance is poor, anti-Special Medium (chilli oil) homogeneity poor, film is difficult to guarantee.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defectives such as the bonding force that has the molybdenumdisulphide lubricant film now is bad, appearance poor, a kind of method of solid lubricant film with molybdenumdisulphide liquid lubricant electricity is provided, adopt the method for galvanic deposit in the piece surface film forming, the consistence of film, homogeneity and bonding force are good, the medium of anti-the feature.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The present invention the method for solid lubricant film with molybdenumdisulphide liquid lubricant electricity: getting solid content is that 10-25%, pH value are that 1000～2000 μ s/cm, solvent are 3～5% molybdenumdisulphide liquid lubricant for 5-7, specific conductivity, cleaning components, part is placed the molybdenumdisulphide liquid lubricant, galvanic deposit 1-5min under voltage 50-90V, temperature 26-30 ℃ condition, then take out part, clean, drain, at the 170-180 ℃ of lower 20-40min that solidifies, can form the molybdenumdisulphide solid lubricant film at part.
Preferably, at first remove greasy dirt and the rusty stain of piece surface, clean, drain with pure water, again part is placed the molybdenumdisulphide liquid lubricant.Take out part after galvanic deposit finishes, clean with pure water, tap water cleans, and drains.
In technique scheme, control voltage, temperature and time in the electrodeposition process well.Voltage is higher, and sedimentation velocity is faster, and rete is thicker, and rete is more black; Otherwise voltage is lower, and sedimentation velocity is slower, and rete is thinner, and rete is more yellow, grows dim.Temperature is higher, and sedimentation velocity is faster, and rete is thicker, and rete is more black; Temperature is lower, and sedimentation velocity is slower, and rete is thinner, and rete is more yellow, grows dim.Depositing time is longer, and sedimentation velocity is faster, and rete is thicker, and rete is more black; Depositing time is shorter, and sedimentation velocity is slower, and rete is thinner, and rete is more yellow, grows dim.The applicant has determined the parameters such as voltage in the technique scheme, temperature and depositing time according to the requirement of product lubricating property.
Compare with the existing method of leaning on the conventional spray paint solid lubricant film to satisfy lubricity always, the present invention is that the method that adopts the electricity consumption of molybdenumdisulphide liquid lubricant forms the molybdenumdisulphide solid lubricant film at the lubricated piece surface of needs, electricity the lubricant film that forms of method have good homogeneity and bonding force, but repeated disassembled and assembled and do not damage lubricant film, can under high and low temperature environment, work, characteristic with anti-Special Medium (chilli oil), guaranteed the oilness under lubricating detail in working order, zero anti-protection against corrosion, kill etc., can be applicable to aviation, space flight, lubricating of all kinds of high-precision bearings in the fields such as boats and ships also can be used in the solid lubrication of other field part.
