Abstract

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.
