摘      要：MX 2 (M=Mo, W; X=S, Se) and DLC (a C: H and WC/C) are the two kinds of typical low friction coatings widely used in industry. The friction and wear properties of these two kinds of coatings marked as MOVIC, MOST, MoSe 2/Ni, WSe 2, a C: H and WC/C coatings were determined by fretting tests in ambient air of different humidity. The results show that the coefficient of friction of MX 2 coatings increases when the relative humidity of air increases whereas the coefficient of friction DLC coatings decreases with the increasing of relative humidity. MOVIC and WSe 2 coatings have a poor friction and wear resistance because of non basal planes (100) and (101) parallel to the surface in the MOVIC coating, or the rough and porous surface of WSe 2 coatings. Among these six coatings, MoSe 2/Ni and WC/C coatings have the highest wear resistance which seems to be unaffected by the relative humidity.
