用于摩擦学研究的原子力显微镜

Frictional force is measured as a function of applied load (friction loops) for several different anti-friction coatings

摩擦和其他损耗在某些应用中(从汽车发动机到髋关节置换)起着关键性的作用,但人们对这些现象仍然缺乏深入的了解。此外,随着临界尺寸的缩小,由于表面积与体积之比的增加,润摩性能会发生显著的变化。原子力显微镜拥有许多适合摩擦学实验(从原子级到微米级)的功能。目前的型号可以在广泛的正交力上测量非常小的侧向力,并且具有更高的力灵敏度和极低的噪音。扫描速度的提高可以在更大的范围内进行速度相关的研究。 凭借这些优势,再加上其他特性(例如:更高的空间分辨率、广泛的环境控制,以及多种设置和数据分析功能),原子力显微镜已成为纳米摩擦学领域的一个强有力的工具。
