对与磨合有关的润滑磨损中波纹度和粗糙度的影响进行了实验和分析。研究发现，润滑滑块形成油膜的能力可以通过表面波纹度来确定，表面波纹度可以用波纹度指数wnand波长参数λ0.5x来表征。接触特性可以由表面粗糙度决定，特别是由表面粗糙度顶点的几何形状决定，表面粗糙度顶点的几何形状可以用塑性指数ψ来表征。似乎wn，λ0.5和ψ一起提供了一个很好的标准来评估润滑磨损。磨合只能改善接触过程中的表面粗糙度效果，几乎不能改变表面波长。
Experiments on and analyses of the waviness and roughness effects in lubricated wear related to running-in were performed. It was found that the ability of a lubricated slider to form an oil film can be determined by surface waviness which can be characterized by a waviness indexWnand wavelength parameterλ0.5x. The characteristic of contact can be determined by the surface roughness, and in particular by the geometry of the asperity summits which can be characterized by the plasticity index ψ. It seems thatWn,λ0.5xand ψ taken together provide a good criterion for assessing lubricated wear. Running-in can only improve the surface roughness effect during contact and hardly changes the surface wavelength.
