METHOD OF ELECTROLYTIC DEPOSITION OF CORROSION-RESISTANT ANTIFRICTION COATINGS BY THE COPPER ALLOY

摘要

FIELD: metallurgy.;SUBSTANCE: method includes the electrolytic deposition of antifriction coatings from a tin-based alloy in an electrolyte containing, g/l: tin (II) borftoride 10-40, copper (II) borftoride 10-25, antimony (III) borofluoride 5-10, cadmium Borftoristy 5-15, zinc (II) borftoristy 5-15, indium (III) borftoristy 2-5, silver (I) borftoriste 0.5-1.5, boron hydrofluoric acid 105-130, boric acid 50-100, antioxidant 1,5-5, surfactant 7-20, with a cathode current density of 2.0-5.0 A/dm² and the temperature of electrolyte 18-25°C.;EFFECT: increase of abrasive and corrosion resistance, strength of coatings in corrosive media, reduction of coefficient of friction, increase of hardness, wear resistance and thermal stability of coatings, while increasing plasticity.;3 cl, 2 tbl
