Discussion of the Paper: Optical In Situ Micro Tribometer for Analysis of Real Contact Area for Contact Mechanics, Adhesion, and Sliding Experiments

摘要

The article by Krick et al. [1], describes an optical in situ tribometer that was used to study the contact area of an elastic sphere loaded against a transparent rigid flat under various loading conditions. A few comments relevant to the presented tribometer and study are in place for the benefit of the readers interested in this field of contact mechanics.
