Effect of aluminium impurities on the oxidation behaviour of iron at room temperature

Surface morphological investigation of iron films during oxidation

“…The rate-determining factors of oxidation can be studied by addition of impurity elements. A1, Si, Cr, Ni, etc have been added to control the oxidation of iron resulting in chemically and structurally modified layers (Wood 1970;Pons et al 1982;Bhavani and Vaidyan 1982). Alloy components have different affinities for oxygen and do not oxidize at the same rate.…”
