摘要
研究了15-5PH型不锈钢热浸镀铝过程中浸镀温度、时间及铝液成分等对浸镀层厚度、镀层表面粗糙度等的影响。结果表明:适宜的浸镀温度为740℃,浸镀时间为4 min。向熔融铝液表面加覆盖剂或在铝液中加入微量稀土Ce、Ga等能有效阻止铝液被氧化,从而形成粗糙度很低且呈银白色光泽的镀铝层。
The effects of dipping temperature, dipping time and aluminum liquid composition on the dipping coating thickness, the surface roughness of 15-5PH stainless steel in the process of hot dipping aluminum were studied. The results show that the suitable dipping temperature and time is 740℃ and 4 min, respectively. Adding cover agent or RE elements Ce, Ga etc. to the surface of molten aluminum can effectively prevent the molten aluminum from oxidizing. Then the aluminum layer with silver shiny and low roughness is formed.
