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