WEAR-RESISTANT DISCRETE COMPOSITE COVERING, METHOD AND DEVICE FORITS APPLICATION ONTO WORKING SURFACE OF ELECTRICALLY CONDUCTIVE DETAIL

摘要

The invention concerns the wear-proof coatings application by means of electric discharges and can be used for risen wear-proof and strength coatings application on the electric conductive parts working surfaces. Here is proposed a composite coating, applied on the electric conductive part working surface and consisting of the wear-proof fragments, plastic deformation-proof fragments and electric conductive part working surface fragments, free of coating, wherein the wear-proof and plastic deformation-proof fragments mentioned above have been fabricated of the material with low friction factor, containing non-ferrous metal, of the viscous metalline material, and also of the solid material, containing ferrous metal: by this the fragments pointed out form a discrete mosaic coating in their combination. Here are also disclosed a method for a composite coating application and a facility for its application, including a generator for electric impulses, the electrode, fabricated of the material, containing non-ferrous metal, with low friction factor, the electrode, fabricated of the solid material, containing ferrous metal, and the electrode, fabricated of the viscous mettaline material mentioned above, mounted on the holder for the electrodes with rotational movement and translation possibility. The invention provides the coating formation on the working part, which is susceptible to tribotechnical wear.
