Outline of Final Research Achievements

In electrical contact elements that are used under micro-vibration conditions, non-conductive wear debris may be formed by tribo-chemical reaction at the contact interfaces, which deteriorate the signal quality. Micro-vibration tribo-tests were performed under various conditions with several electric tribo-elements with new metal-containing DLCs and metallic materials. The results were analyzed in detail and classified into two categories: severe or mild in wear and/or damage. The data of those two categories can be separated in a wear map if frictional force is platted against sliding distance. Its borderline represents an iso-frictional work contour.
