Abstract

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

亚氮钢使用性能指标与表层结构状况的关系
本文介绍了珠光体、马氏体和奥氏体钢和合金采用不同类型的预处理和渗氮方式的组织和摩擦学研究结果。摩擦学试验和金相物理研究的结果使人们能够评估每一种使用的处理方法的有效性,并确定氮化层结构状态的特征,从而有助于提高钢在摩擦和磨损条件下的使用性能。提出了一种综合的摩擦件氮化效率的物理力学评价标准。
