FIELD: restoration of friction units.
SUBSTANCE: method comprises steps of grinding wear traces and further strengthening of female surface by electric spark surfacing with use of graphite electrode in modes with pulse energy in range 0.13 - 0.28 J, specific time interval of strengthening, 1.5 -3 min/sq. cm, oscillation frequency of electrode, 200- 250 Hz; subsequent grinding and lapping.
EFFECT: possibility for increasing useful life period of flat slide valves due to creating irregular roughness on working surfaces in order to provide high oil absorption of coating.
