Influences of temperature, H2SO4 concentration and Sn content on corrosion behaviors of PbSn alloy in sulfuric acid solution

- The increment of solution temperature can decrease the corrosion resistance of PbSn alloy in sulfuric acid solution.
- Sn can increase the corrosion resistance and improve the conductivity of the anodic film on PbSn alloy at 1.28 V in sulfuric acid solution.
- The increment of H2SO4 concentration can increase the corrosion resistance of PbSn alloy and decrease the conductivity of the anodic film on PbSn alloy at 1.28 V in sulfuric acid solution.
- The ascending Sn content in the substrate, decrement of temperature and H2SO4 can enhance the conductivity of the anodic film, and then they can improve the charge-discharge performance of lead acid battery.
