Friction and wear behavior of several functional coatings under lubricated and elevated temperature conditions

摘要

Surface engineering techniques are routinely used for enhancing the performance of a diverse range of products. They are especially beneficial in tribological applications [1-2]. Mo-sprayed coating, nitrided coating and Cr-plated coating are three kinds of typical piston ring materials in IC engines and their tribological performances exert direct influences upon the power output, fuel economy and exhaust emission of the IC engines [3].
