Description

The truncation of surface asperities is considered to prevent excessive wear at the initial stage of sliding contact. However, the quantitative analysis about the effect of truncation on contact characteristics has not been done. In the previous report, truncation was represented by several surface parameters such as skewness of surface roughness profile. In addition, numerical analysis of elastic contact was conducted using numerically generated truncated profiles. The calculated results showed that real contact area increased against the same nominal pressure with the progress of truncation. In this study, several experiments of the contact between the steel ball that has intentionally truncated roughness and an optical glass were carried out. Subsequently, real contact area was measured by means of total reflection method. Finally, previously obtained numerical results were validated in comparison with experimental results.
