An investigation was made of the high temperature oxidation resistance and heat corrosion resistance of Q235 steel treated with hot-dip aluminizing and hot-dip aluminium alloy with various silicon content, the high temperature corrosion resistant properties of the pure aluminium layer and aluminium-silicon alloy layer were compared, the function of silicon element was analyzed. The result shows that the oxidation resistance of Q235 treated with hot-dip aluminizing and aluminium-silicon alloy was almost equal to that of stainless steel, and its heat corrosion resistance was much better than that of stainless steel.
