摘要：

Graphite-like carbon films (GLC) with different metal buffer layers (Cr, Ti, W) were fabricated by direct current magnetron sputtering technique. The effect of metal buffer layer on structure and tribological properties in artificial seawater were carefully investigated. The results show that, in contrast to Ti/GLC and W/GLC film, Cr/GLC film has the highest sp(2) hybridization content, which increases from the top layer to Cr/C interface. The highest sp2 hybridization content promotes graphitization degree of the tribo-film which acts as lubrication phase in the sliding process. The results of potentiodynamic polarization tests show that, in all of three GLC films, Cr/GLC film shows superior corrosion resistance with the highest corrosion voltage (E-corr) of -0.16 V and the lowest corrosion current (i(corr)) of 4.42x10(-9) A/cm(2). As a result, Cr/GLC film presents the best tribological properties in artificial seawater in contrast to Ti/GLC and W/GLC films.
