INFLUENCE OF COMPLEX BORIDE HARDENING ON STRUCTURE AND CHARACTERISTICS OF SURFACE LEVELS OF STEELS FOR PRODUCTION OF DETAILS OF THE SKIDDING FOREST MACHINES GEARS

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.
