Abstract

The operating conditions of forest machines are analyzed. Transmission parts disabled as a result of  intensive wear have been determined, their fracture mechanism has been established. A technique for  diffuse impregnation of  component parts with powdered mixtures containing boron and silicon is offered. An optimal composition and temperature for diffuse impregnation of  component parts operating under dynamic loading has been specified. Micro-hardness of  surface and subsurface layers has been studied.
