This revised volume in the MP Characterization series focuses on surface characterization, including roughness, hardness, coating thickness and bond strength. New advancements in characterization methods are also covered for applications in magnetic recording media, rolling contact bearings and other high-tech systems. Tribology, the study of friction, is vital to a wide variety of engineering areas. The ablility to measure and visualize the surface properties that affect friction is vital. This second edition will bring the reader up to date on the latest characterization methods that are particularly useful for studying surface morphology and molecular structure.
