点击翻译按钮获取中文摘要

This research aims at establishing the hard carbon film which distributed nano cluster metal inside as smart coating which can be adapted for extreme environment. The hard carbon film which controlled environment-proof nature and electrical conductivity has the possibility as new smart coating.The following items became clear with this work.1)Correlation between the nanoscale contact mode of a hard carbon film, and an electrical conduction mechanism.2)Evaluation of the high vacuum environmental friction wear characteristic of a hard carbon multilayer film.3)The proposal of the electrical conduction model of a hard carbon film.
