The technology of finish plasma strengthening (FPS) with the multi-layer nano-coating of the Si-O-CN system as applied to the friction surface strengthening in spherical journal bearings is considered. This method relates to the processes of tubeless chemical precipitation of coatings at atmosphere pressure with the use of volatile fluids of element-organic compounds and gas environment with the simultaneous activation of a surface by electroarc plasma. The essence and distinguishing features of FPS are analyzed. Tribological characteristics of an applied wear resistant antifriction coating are investigated which stipulate for wear resistance increase in spherical journal bearings.
