Chromium coatings bath composition

Corrosion Protection by Metallic Coatings 581 Tab. 9 Composition and working conditions of some chromium-plating baths... [Pg.581]

A buildup of Al + in the zinc phosphating baths will restrict the amount of coating formed unless these ions are ranoved by addition of fluoride or borate. An advantage of zinc phosphating, however, is that it avoids the use of toxic hexavalent chromium compounds. Some simple bath compositions for zinc and manganese phosphating of aluminium are... [Pg.1068]

Fluoride is included in the bath in order to prevent the precipitation of chromium in the coating, by forming soluble CrF3. Typical compositions are... [Pg.1068]
