摘要:
针对众多运动部件存在严重的摩擦磨损问题，使用大气等离子喷涂（APS）设备在1Cr18Ni9Ti不锈钢金属基材上喷涂制备WC(W,Cr)2CNi和WC(W,Cr)2CNi/Ag两种防护涂层，使用CSM摩擦磨损试验机考察两种涂层在室温下与Si3N4球配副时的滑动摩擦磨损性能。结果表明：Ag相的添加可明显降低涂层在干摩擦条件下的摩擦因数，并能减轻涂层的磨损程度；APS制备的WC(W,Cr)2CNi/Ag复合涂层不仅具有优良的自润滑性能，而且具有极佳的耐磨性能，有望作为一种新型耐磨自润滑涂层材料。

Abstract:
Aiming at severe frictional wear problems of many moving parts, the WC(W,Cr)2CNi and WC(W,Cr)2CNi/Ag protective coatings were deposited on 1Cr18Ni9Ti stainless steel substrates by atmospheric plasma spray (APS) technology. The sliding friction and wear behavior of the coatings sliding against Si3N4 balls at room temperature was evaluated by a CSM friction and wear tester. The results show that the addition of Ag phase significantly reduces the dry sliding friction coefficient of the WC(W,Cr)2CNi/Ag composite coating, and obviously relieves the wear degree of the coating. The WC(W,Cr)2CNi/Ag composite coating prepared by APS technology not only has a low friction coefficient, but also possesses a good wear resistance, and the coating is expected to be a new wear resistant and selflubricating coating material.
Key words:  atmospheric plasma spray (APS)  WC(W,Cr)2CNi  Ag  dry sliding  selflubricating
