%X ti alloys are being developed to be used in orthopedic implants due their mechanical properties, biocompatibility and corrosion resistance. at this paper are reported electrochemical studies on the as-cast ti-mo alloys with 6, 10 and 20 mo (wt.%), in 0.15 mol/l na2so4 solution and ringer physiological solution. analyses of the rest-potential indicated that all alloys present the same tendency to a spontaneous passivation, while cyclic voltammograms showed not transpassivation up to potentials of 8,0 v (vs ecs), indicating high corrosion resistance. the comparison among open-circuit profiles of the anodic oxides growth in ringer and na2so4 solutions, are showing that the presence of chloride ions during the anodization is not influencing the oxides chemical stability.
