Tinrich binary alloys, as Sn-Ag, Sn-As, Sn-Fe, Sn-Hg, Sn-Mg, Sn-Mn, Sn-Ni, Su-P, Sn-S, Sn-Se and Sn-Si, were prepared and their corrodibilities in HCl, H2SO4 and HNO3 solutions were tested. The results obtained are shown in Tables 1 to 5. Experiments on anodic behavior of Sn-Bi alloys in NaCl solution were also undertaken.
