摘要
通过铺展实验研究Ti-Cu合金钎料中Ti含量对合金钎料润湿性的影响,试验结果表明,当Ti的质量分数为12%~16%时,合金钎料对C/C复合材料坯体有好的润湿性.用Ti-Cu合金钎料对C/C复合材料进行真空钎焊,研究钎焊接头的组织成分及分布.结果表明,钎料层与C/C复合材料结合紧密,Ti在钎料层与C/C复合材料的界面处富集并形成TiC,同时对Ti-Cu合金钎料的润湿性机理进行了分析.
By using the spreading test method, the effect of Ti additives on the wettability of Ti-Cu alloys was studied. The alloy with 12%~16% titanium exhibited good wettability on the surface of C/C composite green body. Vacuum brazing of C/C composite using Ti-Cu solder alloys was carried out. The microstructure of the welded joint was studied. A diffusion layer formed between the filler metal layer and C/C composite, in which TiC phase was found due to the diffusion of Ti. The mechanism of the improvement of wettability was also analyzed.
