摘要：
Three kinds of diamond-like carbon (DLC)-based films of a-C, a-C:H and a-C:Cr were deposited by unbalanced magnetron sputtering technique on 316L steel and Ni60C spray-welding coating on 316L steel. Tribocorrosion resistance in 5% (mass fraction) sulfuric acid solution of two different protective systems was investigated. The results indicate that the carbon-based films deposited on Ni60C spray-welding coating show a significant improved adhesion and wear resistance compared with the one deposited on 316L. The friction coefficient and corrosion wear rate of the DLC films deposited on Ni60C spray-welding coatings are 0.05 similar to 0.14 and 0.66x10(-8) similar to 5.7x10(-8) mm(3)/N.m, respectively. The improvement of abrasion resistance of composite system is attributed to the Ni60C spray-welding coating as a hard support layer which can improve the bearing capacity of the DLC films, and the graphitization process of DLC films in the process of tribocorrosion test is effectively inhibited.
