ABSTRACT:
The electroless deposition of nickel coatings on metals and metal alloy is accomplished with aqueous baths which contain 10-50 g/l of a fluorine-containing nickel compound; 40 to 200 g/l diammonium hydrogen citrate; 20 to 100 g/l ammonium hydrogen difluoride; 5 to 50 g/l 2-hydroxy-4-methyl benzoic acid, (2,4-cresotinic acid); 0.0005-0.05 g/l copper salt; and 10-100 g/l sodium hypophosphite. Nickel fluoride and nickel (II)-hydroxide carbonate dissolved in hydrofluoric acid have been found particularly advantageous. Smooth and uniform, corrosion-resistant coatings are obtained also on complicated formed parts of magnesium and magnesium alloys.
