Corrosion Studies on Nickel-Iron Electrodeposits

SummaryThe corrosion resistance on brass and steel substrates of chromium finished electrodeposited nickel- iron alloys in the range 0 to 45% iron has been assessed by the acetic acid salt spray test to BS 1224 Appendix K evaluated according to BS 3745 (ISO 1462). Alloys containing up to 30% iron passed the requirements for BS 1224 service conditions 1 and 2; those with higher iron corroded more rapidly, but up to 40% iron would be satisfactory for many interior applications.
