Fe(WC)/Ni(WC)复合涂层摩擦磨损性能研究
|
摘要
采用双丝电弧喷涂技术制备了Fe(WC)/Ni(WC)复合涂层,使用扫描电子显微镜对涂层的显微组织形貌及对应的EDS Mapping映射进行了分析。同时重点研究了摩擦频率和载荷等不同摩擦参数对复合涂层摩擦磨损性能的影响。使用高速往复摩擦磨损试验机和高精度电子分析天平测试了不同摩擦频率和载荷下复合涂层的摩擦系数和磨损量变化,对比分析了摩擦频率和载荷对复合涂层摩擦磨损性能的影响规律。结果表明:Fe(WC)/Ni(WC)复合涂层组织致密,呈典型的层状组织结构,涂层中各元素镶嵌均匀分布,无元素富集现象。当载荷一定时,随着摩擦频率的增大,摩擦系数和磨损量均呈上升趋势。摩擦频率为2 Hz时,摩擦系数最小,磨损量最大。摩擦频率从2 Hz增至6 Hz时,摩擦系数和磨损量均增加。当摩擦频率一定时,随着载荷的增加,摩擦系数降低,磨损量升高。载荷为5N时,摩擦系数最大;载荷为15 N时,磨损量最小。载荷从5 N增至45 N时,摩擦系数降低,磨损量增加。分析可知,Fe(WC)/Ni(WC)复合涂层受摩擦频率的影响较小,载荷对其摩擦磨损性能的影响更为显著。
This work prepared a new Fe(WC)/Ni(WC) composite coatings using twin-wire arc spraying technique and mainly studied the effects of different friction parameters including friction frequency and load on the friction and wear properties of composite coatings.The variation of friction coefficient and wear loss of composite coatings under different friction frequency and load were investigated with high-speed reciprocating friction and wear tester and high precision electronic balance,and the effects of load and friction frequency on friction and wear performance of composite coatings were comparatively analyzed.The results show that the friction coefficient and wear loss are increasing with the increase of friction frequency when the load is constant.When the friction frequency is 2 Hz,the friction coefficient is the minimum,and the wear loss is the maximum.As the friction frequency increases from 2 Hz to 6 Hz,both friction coefficient and wear amount increase.At a constant friction frequency,with the increase of load,the friction coefficient shows a decreasing tendency,and the wear loss shows an increasing tendency.Under the load of 5 N,the friction coefficient is the maximum,and when the load is 15 N,the wear loss is the minimum.When the load increases from 5 N to 45 N,the friction coefficient reduces and the wear loss increases.Thus,compared with the friction frequency,the effect of load on the friction and wear properties of Fe(WC)/Ni(WC) composite coatings is more significant.
