Considerable efforts are being made to improve the life of galvanised steel suhstrates. Electrodeposited zinc alloy containing nickel or cohalt playa significant role in this aspect and most of the galvanising industries abroad have switched over to these modified processes. ]n addition to offering increased service life they are considered as viable alternative to poisonous cadmium deposits also. Notwithstanding the extensive corrosion testing of these coating under simulative conditions in the laboratory, an elaborate programme of a field testing these superiority over conventional zinc deposit both in the passivated and un-passivated conditions wa.<; performed for 18 months under severe tropical marine conditions at Mandapam Camp. The results confirm that zinc 15% nickel alloy deposit are superior and zinc 1% cobalt deposit are much hetter than zinc deposit<; with respect to their corrosion resistance.
