FIELD: application of metallic coatings, possibly chemical deposition of composition type copper coatings onto steel parts that may be used in electric, chemical industry branches, in machine engineering.
SUBSTANCE: solution contains copper sulfate, sodium potassium tartrate, sodium sulfate, sodium hydroxide, Formalin, Aerosil and 20% aqueous solution of polyacrylamide at next relation of ingredients (g/l): copper sulfate, 4 - 5; sodium potassium tartrate, 20 - 22; sodium sulfate, 15 - 16; sodium hydroxide, 10 - 12; Formalin, 20 -24; Aerosil, 0.2 - 0.3; 20% aqueous solution of polyacrylamide, 0.5 - 3.
EFFECT: improved wear resistance, corrosion resistance in sea atmosphere due to increased thickness of coating, lowered friction factor.
