Morphology: Texture, Shape, and Color of Friction Surfaces and Wear Debris in Tribodiagnostics Problems

Fundamentals and methods of morphological analysis of images of friction surfaces and wear debris are discussed in terms of practical problems of tribodiagnostics. A review of widespread approaches to the description of texture, shape, and color of tribological objects is presented. Their parametrical models and methods of classification of morphological types related to the mechanisms of operational degradation of the friction surface are considered. In addition, basic trends of development of morphological analysis methods in the investigation of friction and wear are discussed.
