Hi All, I am looking into anit-friction coatings, wear resistant coatings and corrosion resistant coatings. The primary purpose is anti-friction. Does anyone know if there are materials out which provide no or very less friction. I am mainly interested in thin film coatings by reactive sputtering process eg. Oxides, oxynitirde or nitirdes. Any help will be really appreciated. Thanks and best regards, Ghauri
