Dependence of indicators of nitrited steels operational properties on the surface layer structural condition

The results of structural and tribological studies steels alloys pearlite, martensitic austenitic classes using dif-ferent types pretreatment nitriding modes are presented. tests metallophysical made it possible to evaluate the effectiveness each used treatment methods identify characteristics state nitrided layer, contributing an increase in operational properties friction wear conditions. A comprehensive physical mechanical criterion has been developed components nitrid-ing efficiency.
