ABSTRACT

Low-friction materials and their coatings have been in use for

many decades to control friction and wear in a wide range of

tribological applications. Due to their multifunctional nature, they

have also been very effective in combating corrosion, fatigue, scuff-

ing and fretting-related mechanical failures under harsh operating

conditions [1-9]. Latest self-lubricating coatings consist of nano-

composite and/or -layered morphologies that afford much longer

wear life as well as superior resistance to oxidation and heat-related

degradations. These novel coating architectures are made of two or

more distinct phaseswith each phase providing a range of additional

functionalities besides providing low friction and wear. With recent

advances in deposition technologies, production of such coatings

has now become rather easy and affordable for a wide range of

mainstream applications.
