SOME CONSIDERATIONS ON ELECTROCHEMICAL AND CHEMICAL METAL COVERINGS

This paper briefly presents electrochemical and chemical metallic coatings. Coatings of various parts with metallic layers is done especially for: Increasing the corrosion resistance, improving the appearance, increasing the superficial hardness, increasing the resistance to wear. Metallic coatings can be made: electrochemically, thermally, by spraying, chemically, by plating, amalgamation, by conversion, and by vacuum evaporation.

Keywords: metallic coatings, electrochemical coatings, chemical composition, nickel electrolytes, copper electrolytes Cuvinte cheie: acoperiri metalice, acoperiri electrochimice, compoziție chimică, electroliți de nichelare, electroliți de cuprare
