Abstract

The topographical changes to the asperities of a flat cobalt-hardened gold electroplated surface that occur as a result of being contacted with a ruby sphere are studied by means of scanning tunneling microscopy and software developed to allow computer image registration and subtraction. A range of normal, force loads and sphere sizes are utilized. Quantitative information is obtained for each plastically deformed asperity in the contact region concerning the volume of material displaced during the contact process and the area of the contact spot resulting from the flattened asperity. Three-dimensional images are presented that show the location and size of the portions the asperities that were displaced in the contact process. Two-dimensional maps are generated to show the location and size of the asperity contacting spots in the contact region, Data from contact conditions of 10 to 100 grams normal force and from 1/16 inch to 1/4 inch contacting sphere diameter are used to show trends concerning the number of deformed asperities, total contacting area, total deformed volume, maximum area of the largest deformed asperity, force/total contacting area, and total deformed volume/total contacting area as a function of normal force and sphere diameter.

STM研究加载引起的金接触面形貌变化

利用扫描隧道显微镜和开发的计算机图像配准和减法软件，研究了与红宝石球接触后钴硬化金电镀表面凹凸不平的形貌变化。一系列的正常，力载荷和球体尺寸被利用。对于接触区域中每个塑性变形的凹凸不平，获得了接触过程中位移的材料体积和由平坦的凹凸不平产生的接触点面积的定量信息。三维图像显示了在接触过程中被移位的凸起部分的位置和大小。利用10 ~ 100克法向力和1/16英寸~ 1/4英寸接触球直径的接触条件数据，显示变形凸点的数量、总接触面积、总变形体积、最大变形凸点的最大面积、力/总接触面积、总变形体积/总接触面积作为法向力和球直径的函数。
