The choice of methods of improving wear resistance of vehicles
The study of the destruction of precision friction pair parts was presented and the selection of methods forincreasing their wear resistance was conducted in the paper. The method for producing the coatings with thedesired performance properties was proposed. This method can be implemented practically using the coppercathode, which contains 50% of molybdenum disulfide,which is manufactured from the powder mixture by compression with the subsequent heat treatment. The use of such cathodes allows to obtain the coating, the main components of which are copper and molybdenum disul- fide. At the level of impurities, there is free sulfur, mo- lybdenum, its oxide and molybdenum nitride in the film coating. It is noteworthy that the rate of molybdenum sulfide condensation depends on the substrate tempera- ture more strongly than the rate of copper condensation. This allows directionally affect the ratio of the main components of the film material during its formation. The principles of formation of multicomponent coatings for restoring the precision friction pairs, which take into account the relationship between the technological pa- rameters of the friction process, their structure, mechani- cal and performance properties, were developed.
