FIELD: mechanic working of metals, namely finish abrasive jet working, mainly of precision friction pairs.
SUBSTANCE: method comprises steps of acting upon surface of part with stream of compressed air containing abrasive particles and creating lubricant micro-recesses on worked surface. Lubricant micro-recesses are formed with depth equal to λmax = 1.34 hmax, where hmax - maximum depth of friction surface wear at satisfying relation Flubr/Ffr = 0,45 where Flubr - total area of lubricant micro-recesses, Ffr - friction surface area.
EFFECT: reduced wear degree of friction surfaces of parts.
