Abstract The surface textures have been found effective in improving tribological performance of engineering surfaces. However, the current profiling techniques and parameters are inadequate and/or unsuitable to characterize the textured surfaces. Based on the Abbot-Firestone curve, the RMS deviation and three functional indices describing the bearing and fluid retention properties ( S q , S b i , S c i and S v i ) are reformed to characterize the textured surfaces as well as the normal rough surfaces. The algorithms of the parameters are given and their feasibility is discussed. Comparison is made between the newly developed parameters and the former ones. Experiments are conducted to validate the reformed parameters. It is believed that these parameters are more meaningful in describing the textured surfaces and have a guiding significance for texture design under boundary lubrication.

边界润滑下纹理表面的表征

摘要 已发现表面纹理可有效改善工程表面的摩擦学性能。然而，当前的轮廓技术和参数不足以和/或不适合表征纹理表面。基于 Abbot-Firestone 曲线，对 RMS 偏差和描述轴承和流体保持特性的三个函数指标（S q 、S bi 、S ci 和 S vi ）进行了改造，以表征带纹理的表面以及正常的粗糙表面。给出了参数的算法并讨论了它们的可行性。将新开发的参数与以前的参数进行比较。进行实验以验证改革后的参数。
