The purpose of this paper is to determine the effect of the alloying elements on the passive filmformation on the Ti-Mo-Ni alloy, in concentrated chloride solutions, at high temperatures. Thealloying of titanium with molybdenum and nickel has the following effects on the passivitybehaviour of ternary Ti-0.5Mo-1Ni alloy: the shifting in noble direction of the alloy corrosionpotential due to the couple galvanic effect of the molybdenum and nickel; the enlargement of thealloy passive potential range, as result of the molybdenum and nickel participation with itsinsoluble compounds at the consolidation of the alloy passive film; the decrease of the alloypassive current densities because of the same consolidation effect of the passive layer; both thetitanium and Ti-0.5Mo-1Ni alloy do not present pitting corrosion; the decrease of the alloycorrosion rates in concentrated chloride solutions, in comparison with base metal. |
