Pack cementation diffusion coatings can inexpensively modify the surface chemistry of plain-carbon or low-alloy steels. Excellent adhesion of the coating to the substrate is one of the most distinct advantages of this process. Significant variations in the surface composition can be achieved by a co-deposition process. Various low-carbon and low-alloy steels have been coated by codeposition of Cr + Si and Cr + Al using mixtures of pure metal powders as the sources for these elements. The resistance of these ferritic Fe-Cr-Si and Fe-Cr-Al ferritic coatings to isothermal and long-term cyclic oxidation at elevated temperatures and to aqueous corrosion is reported.
