摘要
采用磁控溅射的方法,利用氩气和甲烷为气源,在中国第一汽车股份有限公司自主研发的发动机配气机构的挺柱上制备类金刚石(DLC)薄膜。利用摩擦磨损试验机和发动机配气机构试验台架,研究了DLC涂层挺柱的摩擦学行为及其对发动机节能的影响。试验结果表明,在边界润滑条件下,DLC涂层挺柱的摩擦因数比原零件降低67%,抗磨损性能大幅度提高;在实际使用工况下,配气机构的摩擦损失降低6%。DLC涂层零件可以降低发动机摩擦损失,适用于汽车低碳技术路线。
The diamond-like carbon （DLC） film was deposited on the valve train tappet of a FAW（First Automobile Works） production engine by dc magnetron sputtering which using methane and argon as the precursors. The influence of the tribological properties of the DLC valve train tappet on engine fuel economy was studied by the test in the universal material tester and the electrically driven valve train test rig. The test results show that friction factor of the DLC valve train was reduced by 67% and the ability of wear resistance was enhanced. Mechanical friction loss of engine valve train was decreased by 6 %. DLC coating of engine component makes engines more efficient, so this technology is suitable for the low carbon technical route.
