Effect of indium alloying in various concentrations with lead on both microhardness and crystallite structure of lead-indium alloy was investigated. The corrosion behavior of leadindium alloys in 4 M H2SO4 acid solution was investigated by Tafel plot and electrochemical impedance spectroscopy (EIS) methods. The results of both Tafel plot extrapolation and EIS measurements exhibited the same trend. Generally, the corrosion ...
