摘　　要：针对材料表面高载荷条件的要求,提出了测量摩擦因数的方法,并进行了相应测试装置的设计,该测试装置由正向加载装置、侧向加载装置和数据处理装置3部分组成。可以用来测量高载荷条件下材料表面的静摩擦因数和滑动摩擦因数,同时得到整个滑动过程中摩擦因数变化情况。利用该装置对某国防减摩涂层进行了测试,结果表明在高载荷条件下该涂层对碳钢表面具有较好的减摩效果。A new method was proposed for material surface friction coefficient measurement at higher pressure, the static and the slippage friction coefficient can be obtained in the testing process. The system is composed three parts： the vertical loading system, the lateral loading system and the data controlling system. Friction coefficients were studied both for the film and the carbon steel substrate respectively, result shows that the static and the slippage friction coefficient is decreased with the load increasing, and the film has a lower friction coefficient than the carbon steel.
