Evidence is provided which supports the view that the bond between chromia scale and chromium is basically strong and that minor amounts of impurities which are present in the metal can make the bond weak. When taken together with other work, it is shown by these results that if commercial alloys can be produced with low impurity concentrations, the oxidation resistance could be significantly improved.
