The corrosion of iron-nickel alloys in deaerated 1n H/sub 2/SO/sub 4/ in the absence and presence of chloride ions and benzotriazole (BTA) between 23/sup 0/ to 75/sup 0/C has been investigated. A marked decrease in the corrosion rate of the uninhibited alloys in the absence and presence of chloride ions was observed as the iron content decreased from pure iron to 60% Fe at all temperatures. On the other hand, below 60% Fe, the corrosion rate of the alloys did not differ as substantially. Apparent activation energies for corrosion of Fe-Ni alloys in 1n H/sub 2/SO/sub 4/ decreases with increases in nickel content. Benzotriazole was an effective corrosion inhibitor of the Fe-Ni alloys in 1n H/sub 2/SO/sub 4/ even at 75/sup 0/C. (19 refs.)
