Abstract

In this article, carbide-derived carbon coating (CDC) on a substrate of silicon carbide was produced by chlorination at 1000 °C. The influence of dechlorination on the friction and wear of CDC coating sliding against SAE52100 steel was investigated. It was found that dechlorination is crucial and necessary for obtaining good tribological performance of CDC coating against steel. The CDC coatings exhibit excellent tribological performance in air at loads lower than 30 N and provide good protection from wear damage of steel as well. The tribological performance of CDC coating against steel is superior to that of commercially available graphite.
