Characterization of Engineered Surfaces
The tribological performance of modified surfaces of the substrate is affected by a) soundness, b) metallurgical, and c) mechanical properties. Need of characterization of the modified surfaces is given in the beginning of the chapter. Techniques of measuring the depth of modified zone, surface roughness, non destructive testing for evaluation of the integrity of modified surfaces have been presented. Methods for hardness and bond strength testing are elaborated. Additionally, techniques for examining the chemical composition, metallurgical properties, and wear behavior have also been described along with typical set of parameters.
