【摘要】 以Q235较理想的热浸镀铝工艺参数为基础,通过二元正交回归试验方法,研究得出较理想的高温扩散渗铝工艺参数,即扩散温度950℃,时间6h。最优工艺参数下表面铝层和扩散铝层的共同厚度为32.8μm,铁铝化合物的平均厚度为16.8μm。同时对热浸扩散渗铝试样进行了900℃×100h高温氧化研究,结果表明,采用最优化工艺参数扩散渗铝,所得扩散渗层分布均匀,抗高温氧化性能显著提高。更多还原

【Abstract】 this paper bases on ideal optimization technological parameters of hot dip aluminizing of Q235.Through orthogonal regression experimental method,studying better technological parameters of diffusion aluminizing.At the same time,we study the high-temperature oxidation properties of diffusion aluminizing sample bases on 900 ℃×100 h.The results show that:diffusing aluminizing bases on optimization technological parameters,the aluminizing layer is uniform and has batter high-temperature oxidation properties.更多还原
