Electrochemical corrosion behavior, microstructure, elastic modulus, Vickers hardness, internal friction and electrical resistivity of lead- calcium rapidly solidified alloys have been investigated. Elastic modulus of Pb99.5-xCa0.5+x (x=0, 0.1, 0.2, 0.3, 0.4 and 0.5 wt. %) alloys increased with increasing Ca content. Also internal friction values of Pb99.5-xCa0.5+x alloys variable decreased with increasing Ca content. But Vickers hardness and thermal diffusivity values of Pb99.5-xCa0.5+x alloys variable increased with increasing Ca content. Electrical resistivity values of Pb99.5-xCa0.5+x alloys decreased with increasing Ca content. The corrosion potential of Pb and Pb99.5-xCa0.5+x (x= 0.2 and 0.5 wt. %) alloys exhibited a negative potential. Also the cathodic and the anodic polarization curves also showed similar corrosion trends. The corrosion resistance of Pb99.5-xCa0.5+x alloy in 0.25 M HCl increased with increasing Ca content ratio. The Pb99Ca1 alloy has best properties for storage battery grids.
