ABSTRACT
Commercially supplied electrolytic chromium has a number of inherent defects and impurities including a substantial amount of oxygen. Coupons of electrolytically deposited chromium have been heat treated at various temperatures in order to study the development of the metal microstructure and to optimise the removal of oxygen from the metal. The effect of these impurities on the oxidation behaviour of chromium is discussed. In situ observations of chromium oxidation have been made in a transmission electron microscope and the results have been presented.
