• The oxide scales formed on impure nickel and high-purity nickel by heating in air at 1100℃ are compared. Multiple layers, particularly triple layers in this work, are observed to be formed on the impure nickel. It is shown, by microhardness measurements and electron probe microanalyses, that the chemical composition of the different oxide layers is not the same. The ratio between the oxygen and the nickel content is larger in the outer layer than in the inner layer. On the other hand, the oxide scale formed on the high-purity nickel consists of one homogeneous layer. Some points of view on the mechanism of oxidation are discussed.
