摘　　要：利用扫描探针显微镜考察了硅基材料的摩擦磨损性能,同时考虑了环境因素、循环扫描次数的影响;通过实验设计,得出了该材料表面的形貌,初步分析了其摩擦磨损性能。结果表明:压电陶瓷的滞后效应和非线性效应的影响比较显著;随着外界湿度的增加,湿度对材料表面黏附力和摩擦系数有较大的影响;外加载荷和扫描循环次数直接决定材料表面的耐磨性能。The adhesive and tribological properties were studied with an atomic force microscope （AFM）. Meanwhile, the effects of relative humidity and scanning cycles were taken into consideration. In addition, a resolution was tried to be proposed. The results indicate that the effects of hysteresis and nonlinearity of the piezo-tube are significant on the friction measurement with the AFM. The relative humidity exerts great influ- ence on the adhesion and friction coefficient of the surface when it goes larger gradually. Moreover, the applied load and sliding cycles directly determine the wear property of the silicon-based material.
