A comparison of methods for determining wear volumes and surface parameters of spherically tipped sliders

The purpose of this paper is to investigate some of the methods of determining the wear volume and geometric surface parameters of a scar resulting from sliding either a sphere or spherically tipped pin on a nominally flat surface. There are several broad classes of methods for making this type of m...

Summary:The purpose of this paper is to investigate some of the methods of determining the wear volume and geometric surface parameters of a scar resulting from sliding either a sphere or spherically tipped pin on a nominally flat surface. There are several broad classes of methods for making this type of measurement. In this paper we will briefly describe these classes in general and then use abrasive wear data to illustrate three specific techniques in detail: two-dimensional analysis, done either manually or with an image analyzer; three-dimensional analysis where the X, Y, Z points came from a stylus-type profiling instrument; three-dimensional analysis where the X, Y, Z points were estimated from a two-dimensional projection obtained from a specially programmed image analyzer.
