摘　　要：针对微观条件下材料表面的摩擦学特性与宏观条件下材料表面的摩擦学特性具有很大差别而国内外在该方面研究较少的现状,提出了一种对微观条件下材料摩擦学性能测试的方法并研制出专用仪器———微摩擦测试仪。详细介绍了测试仪的工作原理,并利用该仪器对铝和铜的表面进行了测试。结果表明:利用该方法研制的测试仪精度高,系统性能稳定,符合微观条件下材料表面的测试要求。Facing the fact that there are significant differences between the tribological performances of the material surface under microscopic and macroscopic conditions and little research has been made in this respect, a measurement method for the micro-tribological performances of the material surface was suggested and a special apparatus was developed. The working principle of the developed microtribological test apparatus was described and the detailed experiments were done with the apparatus for the surface friction of Cu and Al. The results show that the apparatus is characterized by the stable performance, the high precision and well keeping up with the demand of the micro-tribological measurements.
