Abstract
Influence of heat treatment modes on tribotechnical characteristics of working mating arrangements of hardfaced crank¬shafts operating under conditions of metal against metal friction with lubrication was assessed. It is shown that tempering temperature influences quantitative ratio between pearlite and carbide-cementite phases in structure of the deposited metal and its wear resistance.
Keywords: arc surfacing, deposited metal, structure and hardness, tribotechnical characteristics, heat treatment
