Abstract FeS/SiC composite coatings have been successfully produced by plasma spray technique. SiC particles with nano-scale are uniformly distributed in FeS matrix. There is a good bond between the coatings and 40Cr steel substrate. The tribological properties of FeS coating and FeS/SiC composite coatings have been investigated. The results show that FeS/SiC composite coatings have good antifriction and wear resistance properties. The friction coefficients of the composite coatings, mixed with nano SiC particles in weight fraction 0.2 and 0.3, are almost same as that of FeS coating under dry sliding, but the wear volume of them is remarkably decreased over the range of an order of magnitude. In oil lubrication, the friction coefficient of FeS/SiC composite coatings is smaller than that of FeS coating. So the composite coatings have superior antifriction property in the case.
