ANALYSIS OF RESIDUAL STRESSES IN THE HARDENED LAYER GEARS SKIDDERS CHEMICAL SINCE THE PROCESSING

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, aluminum and silicon is offered. An optimal composition and temperature for diffuse impregnation of component parts operating under dynamic loading has been specified. Microhardness of surface and subsurface layers has been studied. Technique for abrasion testing is offered, comparative testing of carburized and borated samples has been carried out
