FIELD: engines and pumps.
SUBSTANCE: part operating in sliding contact at lubrication rate is covered with thin film with tribological function. Thin film is applied to the surface containing rough profiles. Roughness of the profile and their average periods have been specified in order to improve tribological properties so that ratio A of values of square of average period of profile (PSM), which is expressed in mcm to roughness of profile (Pα), which is expressed in mcm, as determined by the French standard ISO 4288, exceeds or is equal to: 
EFFECT: obtaining thin film having improved tribological properties.
