PROCESS FORMING ANTIFRICTION COAT ON METAL SURFACES OF FRICTION PAIRS Russian patent published in 2003 - IPC

FIELD: plastic metal working, reinforcement of surfaces of parts. SUBSTANCE: process consists in deposition of layer of high-strength composite materials by electric spark method or plasma sputtering on surface of friction pair after its plastic working. Layer is subjected to plastic deformation with the use of ultrasound, then layer of high-dispersive natural minerals is applied which is also subjected to plastic deformation with use of ultrasound. EFFECT: raised wear resistance of surface, prolonged service life of friction pairs. 2 cl
