摘　　要：通过SEM观察、X射线光电子能谱分析、电化学阻抗谱测定和阳极极化曲线的测试 ,探讨激光熔凝处理对纯铁渗稀土层组织与耐蚀性能的影响。结果表明 ,在一定条件下 ,激光熔凝处理可进一步提高纯铁渗稀土层组织的致密性与均匀性 ,显著提高稀土渗层的耐蚀性。The effect of laser melting treatment on the structure and corrosion resistance of rare earth permeating layer of pure iron was studied by means of SEM, X ray photoelectron spectroscopy (XPS), electrochemical impedance spectroscopy (EIS) and anode polarization test etc. The results show that the laser surface melting treatment improves greatly the homogenization, compaction and the corrosion resistance of rare earth permeating layer under the condition of test.
