In this article the friction coefficients and the wear resistances of MoS 2 TiW protective coatings manufactured on X38CrMoV5‐1 steel samples by using PVD technology are studied. The investigations based on tribometer tests which were carried out in different temperature conditions. The process of deposition of PVD coatings was realized by using multisource, hybrid factory‐scale equipment of type URM 079. This equipment allows for deposition of coatings by the physical method. The tribological tests were performed using a precision high temperature tribometer under ambient and high temperature conditions with a steel and corundum balls as counter‐samples. In this paper the results of these tribological tests are presented. It is shown that the measured friction coefficient of steel samples with PVD coatings is significantly lower than the friction coefficient of uncoated steel. It is also shown that X38CrMoV5‐1 steel samples with manufactured MoS 2 TiW coatings are characterized by very low friction coefficient and high wear resistance.
