本文研究了材料成分对锡液腐蚀行为的影响。对Fe、Fe-5Cr、410（Fe-12 Cr）、430（Fe-18 Cr）、316L钢进行了腐蚀试验，（Fe-17.3Cr-12.3Ni-2.2Mo-1.6Mn）、Mo、哈氏合金C-276（Ni-15.83Mo-15.67Cr-6.28Fe）、Inconel 600（Ni-15 Cr-8 Fe）和Inconel 625（Ni-22 Cr-9 Mo-5 Fe）在773 K液态Sn中进行了250 h的热处理。利用扫描电镜和X射线能谱仪对钢在液态锡中形成的Fe-Sn金属间化合物进行了观察和分析。当钢中Fe含量较低时，IMC的厚度较薄。当钢的Fe浓度较低时，钢由于腐蚀而显示较小的质量损失。钢中Cr在液态Sn中的溶解率小于Fe。Hastelloy C276合金腐蚀的原因是Ni和Cr在液态Sn中的溶解。但由于Ni和Cr在Sn液中的溶解，在表面形成了富Mo层，减轻了腐蚀。Inconel 600和Inconel 625由于Ni 3Sn 4的形成而被严重腐蚀。
The purpose of the present study is to make clear the effect of material compositions on the corrosion behaviors in liquid tin (Sn). The corrosion tests of Fe, Fe-5Cr, 410 (Fe-12Cr), 430 (Fe-18Cr), 316L (Fe-17.3Cr-12.3Ni-2.2Mo-1.6Mn), Mo, Hastelloy C-276 (Ni-15.83Mo-15.67Cr-6.28Fe), Inconel 600 (Ni-15Cr-8Fe) and Inconel 625 (Ni-22Cr-9Mo-5Fe) were performed in liquid Sn at 773 K for 250 h. The Fe-Sn intermetallic compounds (IMCs) which were formed on the steels in liquid Sn were observed and analyzed by scanning electron microscope and energy-dispersive X-ray spectrometer. The thickness of the IMCs was thinner when Fe concentration of the steels was lower. The steels revealed smaller mass losses due to the corrosion when the Fe concentration of steels was lower. The dissolution ratio of Cr from the steels into liquid Sn was smaller than that of Fe. Hastelloy C276 corroded due to the dissolution of Ni and Cr in liquid Sn. However, Mo-rich layer was formed on the surface due to the dissolution of Ni and Cr into liquid Sn, and it mitigated the corrosion. Inconel 600 and Inconel 625 were severely corroded according to the formation of Ni3Sn4.
