二硫化钨薄膜的摩擦学性能研究
|
摘要
对二硫化钨薄膜在304不锈钢基体上的摩擦学性能进行了研究。用直流磁控溅射法在304不锈钢基体上制备了二硫化钨薄膜,该膜层结构致密,与基体的结合力良好,提高了基体的硬度,降低了基体的弹性模量。二硫化钨薄膜中的硫元素与钨元素的质量比为1.582。用往复式球-盘摩擦磨损试验机研究了二硫化钨薄膜在干摩擦下和在聚α-烯烃(PAO)润滑下的摩擦学性能。在干摩擦下,二硫化钨薄膜不仅能有效地降低304不锈钢基片的摩擦因数,而且平稳。在PAO润滑下,二硫化钨薄膜将基体的抗磨性能提高了40倍以上,摩擦因数从0.09下降到0.07,同时表现出自修复效应。在PAO润滑下,二硫化钨薄膜可有效地改善304不锈钢基体的摩擦学性能,延长304不锈钢基体的使用寿命。
The tribological properties of tungsten disulfide film on 304 stainless steel substrates were studied.A tungsten disulfide film was prepared on a 304 stainless steel substrates by direct current magnetron sputtering method.The film structure was dense and the binding force with the substrates was good.So the hardness of the substrates was improved,and the elastic modulus of the substrates was reduced.The mass ratio of sulfur to tungsten in the tungsten disulfide film was 1.582.The tribological properties of tungsten disulfide film under dry friction and lubrication of poly-α-olefins(PAO) were investigated by reciprocating sliding tribometer with ball-on-disk contact geometry.Under dry friction,tungsten disulfide film could not only effectively reduce the frictional coefficient of 304 stainless steel substrates,but also was smooth.Under the lubrication of PAO,the tungsten disulfide film improved the anti-wear properties of the substrates more than 40 times.And the frictional coefficient decreased from 0.09 to 0.07,while it showed the self-repairing effect.Under the lubrication of PAO,tungsten disulfide film could effectively improve the tribological properties of 304 stainless steel substrates,and extended the life of 304 stainless steel substrates.
