Polarization Study of Sn-0.7Cu Solder Alloy in 1M Hydrochloric Solution

Abstract:

Corrosion properties of Sn-0.7Cu solder were investigated in 1 M HCl. The scanning rates used were 0.5, 1.0, 1.5 and 2.0 mVs^-1 to study the aggressiveness level of HCl electrolyte in various environment. The morphological, elemental and structural of the samples were compared before and after the corrosion. Scan rate 1.0 mVs^-1 was chosen as the most optimum scan rate during corrosion analysis. The morphological analysis observed two types of corrosion product which is compacted and loosely-compacted corrosion product after the samples was polarized in 1 M HCl.
