摘　　要：研究了热浸渗铝液中添加微量稀土元素对低碳钢热浸渗铝时铝的扩散系数的影响,结果表明,稀土元素能增大铝原子的扩散激活能,降低铝原子的扩散系数。Effect of rare-earth elements added in hot-dip aluminizing liguid has been studied on the diffusion coefficient of aluminum during hot-dip aluminizing for low carbon steel. The results have shown that the rare-earth elements will increase the diffusion activation energy of aluminum atoms and decrease the diffusion coefficient of aluminum atoms.

关 键 词：热浸渗铝 扩散系数 激活能 稀土
