Abstract:
CrMoN/MoS2 composite coatings were prepared on the surfaces of the CrMoN composite coatings with different Mo contents by means of a low temperature ion sulfurizing process. The structural and mechanical properties of these coatings as a function of Mo content have been studied. SEM analysis shows that the CrMoN coating reveals a dense and compact surface structure, the CrMoN/MoS2 composite coatings display loose grain structures; In the sulfurizing process, a preferential growth does not happen, the sulfide size is inhibited, The products of the reaction between MoNx and S are the main origin of MoS2.Nanoindentation test shows that the hardness and Young’s modulus of CrMoN/MoS2 coatings are higher than that of CrMoN composite coatings.
