An important aspect of engineering surfaces is that they need to be multifunctional as designs of machine components require cheaper, lighter, smarter, longer-wearing, and more environmentally friendly surfaces that see applications that are hotter, faster, highly pressurized, and exposed to other increasingly hostile environments. This can be achieved by use of modern advanced materials and coatings, which now usually are coated systems. This is a challenging area as usually there is antagonism between obtaining low friction and low wear as well as between high corrosion resistance and low wear. This book covers the increasingly important aspect for engineering surfaces to be multifunctional with a focus on tribological applications. It captures the state of the art regarding the emerging needs for multifunctional surface design for controlling wear, friction, and corrosion, as well as having decorative, self-healing, and/or self-sensing capabilities. It focuses on coatings and materials that include CVD diamond, diamond-like carbon, and multilayered and functionally graded systems for a range of engineering applications including machine tools, orthopedic joints, aero-engines/gas turbines, automotive engines, glass windows and walls, and offshore and marine sectors. It is a unique book as it discusses a range of wet- and dry-deposited coatings and multifunctional materials not often seen in one publication. It allows the reader to understand a wide range of design concepts and what is possible to achieve by current surface engineering techniques.
