FIELD: technology of finish treatment of precision friction pairs, mainly bodies of revolution, for example plug gauges, fuel equipment plungers, injector atomizers. ^ SUBSTANCE: proposed method includes degreasing, application of technological fluid and friction brassing. Prior to friction brassing, friction surfaces are subjected to abrasive jet treatment at total rate of abrasive flow of 0.06 to 0.07 g/mm2. As a result, obtaining of copper-containing film on friction surfaces is guaranteed at Ra<=0.04 mcm. ^ EFFECT: enhanced efficiency. ^ 2 cl, 2 dwg |
