Abstract:

CrMoN composite coatings were deposited on the surface of the stainless steel by magnetron sputtering, then were treated by low temperature ion sulfuration. FESEM equipped with EDX was adopted to analyze the morphologies and compositions of the surface, cross-section and worn scar of the sulfuration layer. The valence states of the ?lm surface were detected by XPS. The nano-hardness and nano-modulus of the layer were measured by a nano tester. The results of the friction and wear show that the CrMoN/MoS2 composite coating is a kind of ideal solid lubrication layer and possess an excellent antifriction and wear-resistance.
