The purpose of this book is to show what wear, erosion, and friction forces look like and to suggest ways to reduce their negative effects. Friction, of course, can be negative or positive, depending on what part of a vehicle or device you are referring to (bad in the engine, good in the brakes). Wear and erosion are almost always undesirable. Our objective is to help readers of this text reduce the negative costs in each reader’s particular circumstance. It is the purpose of this chapter to suggest a methodology for selecting a material and process to address the negative aspects of various wear and erosion modes that were presented in early chapters. Our objective is implementation of the tribology information in this text to solve problems. We will discuss solution optimization, methodology, using bulk materials, and surface engineering and laboratory testing.
