Abstract  A simple preoxidizing treatment added between two processes of coat treatment and diffusion treatment increased considerably hot corrosion resistance of a series of ASL-3 type Al-Si coatings, but did not damage any mechanical properties of coating/substrate system. The analyses results indicated that the preoxidizing treatment led to the formation of a dense and thin Al-and Si-rieh oxide film on the surface of the coating. The presence of SiO_2 within the film accounted for the superior hot corrosion resistance of the coating.
