Abstract

To understand the benefits that tribological engineering materials or surface modifications provide, and ultimately to devise better ones, it is necessary to study the topographical, mechanical, physical, and chemical characteristics of surfaces. This paper reviews advanced surface analytical techniques for measuring surface topography and hardness of engineering surfaces. The primary emphases are on the use of these techniques as they relate to measurements of wear volume loss and nanohardness of materials using optical profilometry and nanoindentation in conjunction with atomic force microscopy, respectively.
