ANTI-FRICTION COAT Russian patent published in 2004 - IPC

FIELD: mechanical engineering; forming friction surfaces; sliding and anti-friction bearings. SUBSTANCE: proposed anti-friction coat includes mono-crystal film 1 fastened with base 2 by means of substrate 3. Used as base is steel and titanium nitride is used as substrate 3. Film 1 has mono-crystal structure where adsorption centers are located; these centers interact between each other and between molecules of lubricant 4, thus resulting in structural ordering and forming epytropic liquid crystal layer of lubricant. Used as adsorption centers are groups of chemical elements (O), (H), (N), (OH), (NHx), (OOH); petroleum jelly +0.1% stearic acid or 1% oleic acid is used as lubricant. EFFECT: enhanced wear resistance, score resistance and temperature stability of coat; reduced friction coefficient. 10 cl, 2 dwg, 1 tbl
