Abstract

Our work study the effect of titanium oxide on structure, soldering properties such as melting temperature, wetting process and corrosion behavior of Sn₈₂Bi₁₅Zn₃ alloy. Microstructure of Sn₈₂Bi₁₅Zn₃ alloy changed after adding different ratio from titanium oxide. Lattice microstrain of Sn₈₂Bi₁₅Zn₃ alloy varied (increased) after adding titanium oxide. Melting temperature of Sn₈₂Bi₁₅Zn₃ alloy varied after adding Ti₂O. Sn_81.4Bi₁₅Zn₃sub>(Ti₂O)_0.6 alloy has low melting temperature. The contact angle Sn₈₂Bi₁₅Zn₃ alloy decreased after adding different ratio from titanium oxide. Corrosion resistance of Sn₈₂Bi₁₅Zn₃ alloy varied (increased) after adding Ti₂O. From our results, soldering properties (melting temperature and contact angle) and corrosion resistance of Sn₈₂Bi₁₅Zn₃ alloy improved after adding Ti₂O.
