The aspects of real engineering surfaces are discussed with regard to their three-dimensional nature. A review of potential uses of surface finish measurement methods is discussed for characterization of functional surfaces. Using an optical-based system and a set of specific measurement procedures, two functional surfaces with different roughness were analyzed to illustrate a typical surface topography evaluation. A simple sliding test was then utilized to show that a special finish produced by a proprietary finishing process can provide improved performance, as measured by wear differences, frictional properties and operating temperature of the system. A special surface treatment was then evaluated in conjunction with the special finish in order to enhance its functional load support. Simple sliding test results indicates a potential new engineered surface for improving tribological contact performance.
