Abstract
The study proposes a comprehensive methodology for improving the “center plate – thrust bearing” node, including the treatment of the surface of the thrust bearing by the method of electric spark alloying in I-40 industrial oil with a FUBAG tungsten electrode and the use of plastic lubricants containing effective additives that promote the formation of secondary structures on a metal counterbody. Tribological tests were carried out on a friction machine with 30X13 steel samples after processing by the method of electric spark alloying in the presence of PUMA-MR lubricant. A double calcium and zinc metaphosphate is used as an additive. Using experimental planning methods, the effect of the additive percentage and load-speed conditions on the wear rate was investigated. Optimization of the lubricant additive content made it possible to significantly increase the service life of the friction system under study.
