利用光学干涉法研究弹流润滑已扩展到研究粗糙表面的润滑问题。实验是在一个简单的滑动点接触试验台上进行的。一个带有二氧化钛半反射涂层和二氧化硅间隔层的光滑玻璃板被旋转到一个静态的EN 31钢球上，在这个钢球上已经产生了人造的二维粗糙度。粗糙度的二维性使得研究粗糙度的方向性对弹性流体动力润滑的影响成为可能。此外，还研究了单个粗糙度和粗糙度对的润滑问题。研究结果表明，微弹流体动力润滑微凸体是可能的。横向粗糙对之间的空化效应已经被注意到了。1974年10月8日至10日在加拿大蒙特利尔举行的ASLE/ASME润滑会议上，作为美国润滑工程师学会的论文发表
The use of optical interferometry to study elastohydrodynamic lubrication was extended to a study of the lubrication of rough surfaces. The experiments were conducted using a simple sliding point contact rig. A smooth glass plate with a titanium dioxide semi-reflecting coating and a silicon dioxide spacer layer was rotated over a static EN 31 steel ball on which an artificial, two-dimensional roughness had been created. The two-dimensional nature of the roughness enabled a study of the effect of directional properties of roughness on elastohydrodynamic lubrication to be carried out. The lubrication of single asperities and asperity pairs was also investigated. The results of the study have shown that microelastohydrodynamic lubrication of asperities is possible. Interesting effects of cavitation between transverse asperity pairs have been noted. Presented as an American Society of Lubrication Engineers paper at the ASLE/ASME Lubrication Conference held in Montreal, Canada, October 8–10, 1974
