Abstract The microstructure and chemical composition of the hot impregnated Al-Si coat-ing on 08Al steel sheet were analysed by SEM, EPMA and X-ray diffraction. The coatingis xonstitated by three parts: the outer is an α-Al solid solution of enriched Si and γ- (Fe,Al, Si) phases; the intermediate FeAl_3 and Fe_2Al_5 phases mainly and the inner neighbouringupon the substrate mainly Fe_2Al_5 phase.
