| Abstract | ||||
| The effect of addition of Ca on the structure, thermal, mechanical, electrical and electrochemical properties of Pb-10Sn alloy was investigated for lead acid batteries applications in order to extend the life cycle of the gird by improving its mechanical and corrosion resistance. The material of lead acid battery grid mostly is based on Pb-Sn alloy. In the present work six rapidly solidified alloys of compositions (90-x)Pb-10Sn-xCa (x=0, 0.5, 1, 1.5, 2, 2.5 wt.%), were produced by melt-spinning technique. X-ray diffraction analysis and differential scanning calorimetry have been carried out. Also mechanical, electrical and electrochemical properties were measured. Here we show that the addition of 2.5 wt.% Ca to Pb-10Sn improves its mechanical properties this is evident in the increase of Young's modulus, microhardness number and microcreep behavior and enhances its corrosion resistance. Therefore the rapidly solidified melt-spun 87.5 wt.%Pb-10wt.%Sn-2.5wt.%Ca alloy is the most suitable alloy to be used as a grid in lead acid batteries. | ||||
