【Abstract】 New low-antimony alloys with RE were manufactured.The mechanical properties and electrochemicalperformances were detected and analyzed using tensile test,hardness test,cathodic polarization curves,anodic polarization curves,corrosive weight-loss and gas evolution experiment atroom temperature.The results showed that Pb-Sb-RE alloys with low antimony content have excellent mechanical behaviors and corrosion resistance properties.The addition of RE can not only promote the toughness of alloys, but also improve the corrosion resistance behavior,and the Pb-Sb-REalloys can serve as the candidate of the grid materials for reduced-maintenance lead acid battery.更多还原
