利用射频/直流脉冲( RF/DC pulsed)技术,以气体A-C：H(乙炔)为原料,在高速钢基体(HRC65)和汽车活塞销上制备了类金刚石(Diamond-like carbon,DLC)涂层。采用激光Roman光谱仪研究了DLC的结构组成,利用摩擦磨损试验机测试了不同摩擦副在干摩擦和油润滑环境下的摩擦系数及耐磨寿命,最后用光学显微镜观察了汽车活塞销涂层类金刚石前后的表面形貌。结果表明：采用此方法在汽车活塞销上制备的类金刚石涂层光洁度高,摩擦系数小；摩擦副之间的硬度差对其耐磨寿命具有很大的影响,加入润滑剂可以抵消这种影响；汽车活塞销涂层类金刚石在工作一定时间后,表面粗糙度降低,耐磨寿命提高,同时DLC对摩擦副具有抛光润滑作用,是一种汽车零部件优选的抗磨减磨涂层材料。活塞销涂层类金刚石实际装车现场测试表明,寿命比没有涂层的活塞销提高4.5倍,未来可以作为汽车零部件表面的保护涂层。

Diamond-like carbon( DLC) films are successfully deposited on high-speed steel substrate ( HRC65 ) and automobile piston pin by RF/DC pulse technology using A-C:H ( acetylene ) as the raw gas. The microstructure of DLC coating are investigated by laser Roman spectrometer. The friction coefficient and the anti-wear life of different friction pairs under dry friction and lubrication environment are examined on friction and wear testing machine. The surface morphology of the automobile piston pin before and after running is observed by optical microscope. The preparation of DLC on automobile piston pin is very much smooth and has small friction coefficient. The hardness difference of the friction pairs has a great influence on the antiwear life,but lubricant can offset this effect. After the diamond-like carbon works for a certain time,its surface roughness reduces and its antiwear life of friction increases. The result shows that the DLC is a preferred coating for automobile parts to be resistant to wear due to polishing lubrication and that the life of the piston pin with DLC is 4. 5 times higher than that without coating. The DLC can be used as a protective coating of automobile parts surface in the future.
