Abstract

The running-in period during dry sliding wear might determine the evolution to steady-state wear behaviour. To this end, the running-in period during sliding wear of austenitic stainless steel, AISI 316L stainless steel, and Hadfield steel were studied through the testing pin (flat-ended)-on-disk configuration. The effects of the normal load, sliding speed, and alloy type were assessed, and the specific wear rate and strain hardening characteristics were determined. The wear rate was correlated with wear mechanism, friction coefficient, hardening, and roughness to characterize the changes occurring during the running-in period. These changes could influence the responses of these materials to wear during the steady-state period. The stabilization of the specific wear rate and hardness was noted to align with the end of the running-in period.

奥氏体钢滑动磨损过程中的磨合期
干滑动磨损期间的磨合期可能会决定磨损行为向稳态的演变。为此,我们通过测试针(平头)-圆盘配置,研究了奥氏体不锈钢、AISI 316L 不锈钢和哈德菲尔德钢在滑动磨损过程中的磨合期。评估了法向载荷、滑动速度和合金类型的影响,并确定了具体的磨损率和应变硬化特征。磨损率与磨损机理、摩擦系数、硬化和粗糙度相关联,以描述磨合期内发生的变化。这些变化可能会影响这些材料在稳态期间对磨损的反应。特定磨损率和硬度的稳定与磨合期的结束相一致。
