利用原子力显微镜对石英岩表面单层分子沉积膜的微观摩擦特性进行了研究，发现该分子沉积膜具有一定的减摩性．通过对其表面力－位移曲线、表面形貌像、调制力像和摩擦力像的进一步分析表明，石英岩表面分子沉积膜具有减摩作用的原因在于它能够降低表面的粘着力并对表面具有微观修饰作用． Atomic force microscopy was used to study the microscopic tribological properties of the monolayer deposited films on the surface of quartzite. It was found that the deposited films had some antifriction properties. Further analysis of the surface force-displacement curve, surface topography, modulation force image and friction image shows that the molecular deposition film on the quartzite surface has an antifriction effect because it can reduce the surface adhesion and has the effect on the surface Micro-modification.
