Abstract

Aluminium workpieces are dipped into a bath contg. Cu, Ni and hypophosphite ions so that the aluminium is coated with a Cu-Ni-P alloy to a thickness of 25 mu and then the workpieces are dipped, for 1 min in a second bath contg. 1-5 wt.% chromate ions and having a pH 1.6 and a temp. 30 degrees C. The coatings improve the corrosion resistance of Al.
