Abstract
Fe-Cr-Ni-P alloys were electrodeposited from a sulfate-glycine bath, and a determination of the influence of bath composition on their composition, and of the condition for amorphous formation was made. The polarization behavior of the alloy deposits was investigated in an acidic solution.
It was found that amorphous Fe-Cr-Ni-P alloy deposits were obtained over a wide range of bath compositions. Based on anodic polarization curves in 1N hydrochloric acid at 30°C, it was shown that the presence of chromium and phosphorus in the amorphous alloy deposits have a favorable effect on their corrosion resistance, and that the presence of nickel was effective in increasing the stability of passive films formed in acidic solutions. The same outstanding corrosion resistance was shown under comparision with the anodic polarization curve of Hastelloy C-276.
