Abstract
This work studies the corrosion behavior of β-Sn and intermetallic compounds (IMCs) in Sn96.5Ag3.0Cu0.5 (SAC305) alloy through micro-structure observation, in-situ electrochemical technique and first-principles calculation. The results show that corrosion behavior of SAC305 is affected by galvanic corrosion, electronic structure and material microstructure. The Volta potential difference between Cu6Sn5, Ag3Sn and Sn is up to 234 and 174 mV. The...
