Sn-Ni合金对镀Ti石墨的润湿性的研究

An Investigation on the Wetting of Ti-coated Graphite Surfaces by Sn-Ni Alloys

根据熔融金属/合金在石墨孔内所呈的月牙弯面形状,研究了Sn-Ni 合金对未处理和镀Ti 处理石墨的润湿性。结果表明,镀Ti 处理在石墨表面生成了一层TiC+Ti 膜,从而显著地改善了Sn-Ni 合金对石墨的润湿性。借助电子探针,作者还进一步分析了镀Ti 石墨与Sn-Ni 合金之间的界面组织特征。分析表明,镀Ti 石墨和Sn-Ni 合金之间生成了中间反应层。

According to the convex-concave characteristics of metal/alloys inside the graphite holes,the wetting between Ti-coated graphites and Sn-Ni alloys has been studied in this paper.It was found that Ti-TiC thin films were formed on the graphite surfaces after Ti-coating treatment and therefore resulted into the marked improvement in the wetting of those Ti-coated graphite surfaces with Sn-Ni alloys.The microstructure at the interfaces between Ti-coated grap- hites and Sn-Ni alloys was examined using electron probe analyser.Examination results showed that intermedium reaction layers were formed at the above interfaces.
