In Situ Laser Raman Spectroscopic Study of Anodic Corrosion Films on Nickel and Cobalt

Abstract

In situ laser Raman spectra of anodic corrosion films formed on Ni and Co in have been obtained for the first time and the composition of the surface films deduced. The Raman spectrum of the film found on Ni at about 0.6V vs. corresponds closely to that of hydrated . The anodically formed film on Co at about 0.45V appeared to consist of a mixture of and .
