As designs of machine components require cheaper, lighter, smarter, longer-lasting, and more environmentally friendly surfaces that see applications that are hotter, faster, highly pressurized, and exposed to other increasingly hostile environments, there is a need for engineering surfaces to be multifunctional. This multifunctionality can be achieved by the use of modern advanced materials and coatings. This is a challenging area because usually there is antagonism between obtaining low friction and low wear as well as between high corrosion resistance and low wear. This book focuses on the increasingly important need for
