Principles of Engineering Tribology: Fundamentals and Applications introduces readers to the core theories and fundamentals of the field, its basic terminology and concepts, as well as advanced topics such as the tribological properties of various engineering surfaces, roughness measurements, and the mechanics of surface contact. The fundamentals of friction and wear of metallic and non-metallic materials such as polymers, ceramics, rubbers, and composites are discussed, as are fluidic, gaseous, grease, and solid media lubrication techniques. In addition, the properties of lubricants and various types of additives incorporated are discussed, along with a methodology for conducting friction, wear and lubrication laboratory testing and an overview of simulation and modeling methods for various tribosystems. Case studies and applications are featured throughout, with a particular emphasis on analyzing failure modes of tribosystems.
