Abstract

Electrical contact resistance (ECR) techniques have long been used to study mixed-elastohydrodynamic lubrication (EHL) conditions, where direct metallic asperity contact takes place alongside conditions of very thin lubricant films. This paper presents the results of an implementation of the ECR technique to study realistic mixed lubrication contacts which is capable of identifying individual asperity contact events on a repeatable basis between two superfinished surfaces. The technique is then used to investigate the variation of mean ECR measurements with operating conditions for ground surfaces in contact.
