anti-friction coatings, production methods of such coatings and products including such coatings

摘要

ANTIFRICTION COATINGS, PRODUCTION METHODS FOR SUCH COATINGS AND PRODUCTS INCLUDING SUCH COATINGS. The present invention relates to a coated substrate and a process for forming the coated substrate, including a first layer of oily coating covering the substrate, the first layer of oily coating including a first lubricant providing the first layer of oily coating with a first coefficient friction; and a second layer of oily coating, the first layer of oily coating covering the second layer of oily coating including a second lubricant providing the second layer of oily coating with a second coefficient of friction, in which the second coefficient of friction is greater than the first friction coefficient.
