作者采用金相、扫描电镜、电子探针和X射线衍射等分析技术,对感应料浆法渗铝钢管渗层的厚度、铝浓度分布、相组成以及焊接区域的组织特征和机械性能进行了试验研究。试验结果表明,渗层中不存在含铝较高的脆性相,再经炼油厂挂片试验,也证明其抗腐蚀性能良好。 The authors tested the thickness, the aluminum concentration distribution, the phase composition and the microstructure and mechanical properties of the welded zone by inductive slurry method using metallographic, scanning electron microscopy, electron probe and X-ray diffraction techniques. the study. The test results show that the infiltration layer does not exist in the high brittle phase of aluminum, and then through the refinery coupons test, also proved its good corrosion resistance.
