摘要

为探究四面体非晶碳(ta-C)薄膜与几种典型对偶材料的摩擦学性能的变化规律及相关机理,采用新型激光引弧磁过滤真空阴极电弧技术制备厚度约为1 μm 的ta-C 薄膜,选用WC、Al2O3、9Cr18 3 种高硬度对磨球进行摩擦磨损试验。使用扫描电镜、X 射线光电子能谱、拉曼光谱仪、表面轮廓仪、纳米压痕仪、球盘摩擦磨损试验仪对ta-C 薄膜的微观结构和摩擦学性能进行系统研究。结果表明:3 种对偶材料下,ta-C 薄膜的摩擦系数都很低,均表现出较优异的抗磨减摩性能。其中,当对磨球为Al2O3时,薄膜摩擦系数最低,为0.11 左右;当对磨球为9Cr18时,薄膜的磨损率最小,为4.0×10-7mm3/(N·m);对磨球为WC 时,薄膜的磨损率最高,为7.6×10-7mm3/(N·m)。薄膜的磨损机理主要为磨粒磨损,不同对偶材料表面均生成了具有碳质结构特征和石墨化的转移膜。

Abstract

For studying the changing rules of the tribological properties and the related mechanisms of ta-C film in friction against several typical counterpart materials,a ta-C film with a thickness of approximately 1 μm was deposited by the laser-induced arc magnetic filtered vacuum cathode arc technology,and three kinds of counterpart balls with high hardness (WC,Al2O3 and 9Cr18) were used for friction and wear test.The microstructure and tribological properties of the ta-C film were systematically investigated by scanning electron microscopy,X-ray photoelectron spectroscopy,Raman spectrometer,surface profilometer,nano-indentation tester and ball-disk friction and wear equipment.Results showed that the ta-C film possessed extremely low friction coefficients in friction against all the three counterpart materials,and exhibited excellent antiwear and antifriction properties.When Al2O3 counterpart was employed,the friction coefficient of the film was the lowest with a value of around 0.11;when 9Cr18 counterpart was employed,the film showed the lowest wear rate of 4.0×10-7 mm3/(N·m);and when WC counterpart was employed,the film showed the highest wear rate of 7.6×10-7 mm3/(N·m). Besides,the main wear mechanism of the film was abrasive wear,and a graphitized transfer film with the characteristics of carbon structure was detected on the surfaces of all the counterparts.
