Maintaining the performance of power units of automobile and tractor equipment for a long time is a very urgent task today. In this regard, work is being carried out to develop and master the technology for applying advanced coatings to increase surface hardness. However, the development of coatings that increase wear resistance is inextricably linked with research aimed at studying the properties of the coatings themselves, as well as their impact on the performance of the products themselves. To ensure long-term and trouble-free operation of units with friction pairs, not only advanced coatings are used, but also methods for applying special microrelief, protective materials and lubricants. Many scientific schools are working on solving the problem of increasing resources. Each approach involves testing and calculations. This paper shows the effect of ceramic coating on the service life of the crankshaft of a KamAZ vehicle engine. This paper examines the possibility of using a ceramic coating as a means of protecting the crankshaft journals from wear. Data from studies on increasing the service life of friction pairs are presented. Dependencies that characterize the wear rate are presented. A fragment of a method for calculating crankshaft deformations caused by residual stresses is proposed.
