A computer model of the adsorption process of lube oil molecules on friction surfaces reveals that carbon monocrystalline coatings with a strongly orientating effect promote the level of molecular orientation in boundary layers contrary to the amorphous ones because there is no essential orientating effect on these layers. The results of lab tribological tests of carbon coatings deposited on steel surfaces in some model oils corroborate that the coatings with a higher level of orientation ability yield better lube properties.
