纳米二维黑磷的PTFE薄膜涂层的制备及其摩擦性能研究
|
摘要
采用旋涂法在7050铝合金表面制备了内含0、1.3%、3.8%纳米二维黑磷的聚四氟乙烯(PTFE)薄膜涂层。选择载荷为1N(接触压力为501MPa)、2Hz频率和5.3mm滑动行程条件下(平均线速度为21.2mm/s),使用球-盘摩擦仪进行摩擦磨损试验。利用环境扫描电镜(ESEM)和三维白光显微镜分别对涂层磨痕形貌和磨损率进行表征。黑磷含量为1.3%和3.8%的PTFE涂层的摩擦系数(COF)分别降低了23%(COF:0.079)和27%(COF:0.074),其磨损率分别从2.554×10~(-4) mm~3 N~(-1) m~(-1)降至0.758×10~(-4) mm~3 N~(-1) m~(-1)(降低70.3%)和0.156×10~(-4) mm~3 N~(-1) m~(-1)(降低93.8%)。结果表明,纳米黑磷材料与PTFE的复合膜不仅具有较好的润滑作用,而且能有效提高PTFE的耐磨性。
Polytetrafluoroethylene(PTFE)film coatings with 0,1.3%and 3.8%naro-two-dimensional black phosphorous were prepared on 7050aluminum alloy by spin coating method.The friction wear test was carried out by using ball-on-disk tribometer with the selection of load as 1N(contact pressure:501 MPa),2Hz frequency and 5.3mm sliding displacement(mean linear velocity 21.2mm/s).Three-dimensional white light and environmental scanning electron micro-scopy(ESEM)were used to characterize the wear amount and morphology of the coatings.The coefficient of friction(COF)of PTFE coatings with black phosphorus content of 1.3%and 3.8%decreased by 23%(COF:0.079)and 27%(COF:0.074),respectively,while the wear rate decreased from 2.554×10~(-4 )mm~(3 )N~(-1 )m~(-1 )to 0.758×10~(-4 )mm~(3 )N~(-1 )m~(-1)(decreased by 70.3%)and0.156×10~(-4 )mm~(3 )N~(-1 )m~(-1)(decreased by 93.8%).The results show that the black phosphorus and PTFE composite with 2-D layered and unique honeycomb structure can not only provide good lubrication,but also greatly improve the wear resistance of PTFE.
