Abstract

In an investigation for developing Pb-free Al-Zn-Sn solders, indium was added to lower the melting point of the solders. The melting point of a 10In-9(5Al-Zn)-Sn solder was found to be 192°C when measured with differential scanning calorimetry. Meanwhile, the potentiodynamic electrochemical behaviors of thus prepared In-Al-Zn-Sn solders in a 3.5% NaCl solution were explored. The investigated solders exhibit electrochemical passivation behaviors. The corrosion products formed during the polarization study were characterized with scanning electron microscopy and X-ray diffraction. The corrosion products formed, depending on potential, during polarization were found to be ZnO, SnO, SnO2 and Sn3O4.
