Abstract

Films containing cobalt, such as CoP, FeCoCr and CoCr films, which are formed on a substrate can be treated for corrosion resistance by dipping in a hot solution of sodium dichromate, followed by rinsing with de-ionized water and drying. The treatment deposits an extremely thin, transparent, corrosion-protective layer over the cobalt-containing film.
