摘要：

Hot dipped aluminising (HDA) of a low carbon steel wire was carried out using different preheating temperatures and withdraw rates. In all cases, a coating layer was formed, composed of an intermetallic layer and an aluminium overlayer. For the best quality coating, a relationship between preheating temperature and withdraw rate of the steel wire from the aluminium bath was determined as T = - 0.31W(2) + 16.2 W + 215. Coating thickness increased with withdraw rate, following a parabolic relationship. SEM-EDAX analysis revealed that the intermetallic layer consisted primarily of Fe2Al5. The effects of preheating temperature on coating quality, corrosion resistance, and mechanical properties of the coating were studied. It was proved that using a cooling system could partially eliminate the decrease in strength generated by the HDA process.
