Sliding friction and wear of DLC coating films in hydrogen environment

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The fundamental processes occurring with diamond-like carbon (DLC) sliding in hydrogen were studied. Sliding tests of two DLC coating films were conducted in various gas environments including hydrogen and chemical analysis of the sliding surfaces were made. Sliding test results of the a-C:H DLC showed low coefficient of friction below 0.1 in dry air and hydrogen. The ta-C DLC showed lower coefficient of friction and specific wear in hydrogen than in other environments. Low coefficient of friction depended on oxygen content on the sliding surfaces. ta-C DLC graphitized less in hydrogen than in the other environments, which resulted in the low friction. This is an abstract of a paper presented at the Proceedings of World Tribology Congress (Kyoto, Japan 9/6-11/2009).
