Improved frictional behavior of SiC derived carbon coating using MoS3 as a solid lubricant.

Frictional behavior of carbide-derived carbon (CDC) coatings on SiC was modified by using MoS 3 as solid lubricants in two forms, i.e. a powder lubricant and a lubricating additive. As the powder lubricant, MoS 3 was unfavorable for the tribological behavior of CDC coatings. Moreover, its friction and wear behaviors were worse than that of MoS 2 . As the lubricating additive, MoS 3 was in-situ prepared within CDC coatings to obtain two kinds of CDC-MoS 3 composites with different microstructures. The CDC-MoS 3 composites showed lower friction than untreated CDC coatings and their tribological behavior was significantly affected by the microstructures. [ABSTRACT FROM AUTHOR]
