文摘

Frictional behavior of carbide-derived carbon (CDC) coatings on SiC was modified by using MoS₃ as solid lubricants in two forms, i.e. a powder lubricant and a lubricating additive. As the powder lubricant, MoS₃ was unfavorable for the tribological behavior of CDC coatings. Moreover, its friction and wear behaviors were worse than that of MoS₂. As the lubricating additive, MoS₃ was in-situ prepared within CDC coatings to obtain two kinds of CDC-MoS₃ composites with different microstructures. The CDC-MoS₃ composites showed lower friction than untreated CDC coatings and their tribological behavior was significantly affected by the microstructures.
