摘要

我们建议使用 AuSn20 填料来提高 TA9/Sn-6Zr/ZrO2 接头的结合强度和耐腐蚀性。为了评估其可行性，我们研究了两个 TA9/ZrO2 接头的界面微观结构、机械性能和耐腐蚀性。结果表明，加入 AuSn20 填充剂后，钎缝从脆性的、功函数较低的β-Sn 和 ZrSn2 相转变为韧性的、功函数较高的 AuSn2 和 AuSn4 相，显著提高了 TA9/ZrO2 接头的抗剪强度和耐腐蚀性。TA9/ZrO2 接头的腐蚀产物主要是 SnO 和 SnO2，还有微量的 SnCl2、SnCl4 和 Zr(HPO4)2。

Improvement of biocompatible TA9/ZrO2 joint by AuSn20 filler: Interfacial microstructure, mechanical properties, and corrosion resistance

We propose employing AuSn20 filler to improve the bonding strength and corrosion resistance of TA9/Sn-6Zr/ZrO₂ joint. To assess its feasibility, the interfacial microstructure, mechanical properties, and corrosion resistance of two TA9/ZrO₂ joints were investigated. The results indicate that the addition of AuSn20 filler transforms the brazing seam from brittle and lower work function β-Sn and ZrSn₂ phases to ductile and higher work function AuSn₂ and AuSn₄ phase, significantly improving the shear strength and corrosion resistance of the TA9/ZrO₂ joint. The corrosion products of TA9/ZrO₂ joints are mainly SnO and SnO₂, with traces of SnCl₂, SnCl₄, and Zr(HPO₄)₂.
