磨合是机械系统不可避免的重要磨损过程，对延长使用寿命、提高运行性能起着不可缺少的作用。表面形貌是摩擦副的一个重要特征。因此，研究磨合过程中表面形貌的改变对控制表面质量，进而实现机床系统的改进至关重要。为了了解磨合过程中表面形貌的演变规律，本文开展了钢材干滑动磨合试验，并采用面形表面评价参数对磨合过程中的表面形貌进行了评价。结果表明，表面形貌评价可以为钢在干滑动摩擦磨合过程中的磨损状况提供有价值的信息，幅值参数、面积和体积参数以及混合参数在磨合过程中表面形貌变化的表征中发挥着不同的重要作用。
Running-in is an important and inevitable wear process for machine system, and it plays an indispensable role in extending service life and improving operating performance. Surface topography appears as a significant feature of friction pairs. Therefore, study on modification of surface topography in running-in is crucial to control surface quality and then achieve improvement of machine system. In this paper, to understand the evolution of surface topography in running-in process, steel dry sliding running-in experiments were conducted, and surface topographies in running-in were evaluated with the areal surface evaluation parameters. The results reveal that surface topography evaluation could provide valuable information about wear status of steel running-in process of dry sliding friction, amplitude parameters, area and volume parameters, and hybrid parameters play different and important roles in characterization of surface topography modification in running-in.
