An experimental telephone line was erected along the Beach Road, at Visakhapatnam employing NML aluminised M.S. wire. Samples of the aluminised steel wire were taken after six months, one year's and one and a half years' exposure and comprehensively examined. Aluminium coating offered sacrificial protection to steel for over eighteen months as compared to a period of hardly six months which is the maximum life of galvanised wire in such severely corrosive atmosphere. The rust formed, after removal of the aluminised coating, was identified as Fe2O3. The saline atmosphere contained chlorides and sulphates of sodium, magnesium and calcium, which attacked the aluminised coating. Whereas the corrosion products of aluminised wire were fully adherent to the steel base, those of galvanised wire flaked off in service. (Mr. S.M. Arora, Junior Scientific Officer; Mr. A.N.
