Abstract
Newly designed titanium alloys composed of vital elements are being researched to represent alternatives to commercial alloys, and Zr addition to Ti-10Mo alloy is investigated through corrosion tests in saline media. All studied alloys are in the α+β region designed using the d-orbital method after applying the equivalent Mo ([Mo]eq) concentrations equation. The microstructure analysis approved the appearance of α laths and β grains with varied percentages measured from XRD diffraction. The β phase amount in the studied alloys is inversely proportional to the corrosion rate. β phase percentages are 94.6%, 52.5% and 82.3%, opposed to corrosion rates of 0.95451× 10-3, 1.7819× 10-3, and 1.0288× 10-3 mm/year for (Ti-10Mo, Ti-10Mo-3Zr, and Ti-10Mo-6Zr) wt% alloys, respectively. These findings agree with a previous study on Ti-Mo-Zr alloys. Large difference stabled phases induce potential difference, causing micro galvanic cells to result in high corrosion as achieved in Ti-10Mo-3Zr alloy. Zr addition forms a protective layer over implant material, which influences appeared in Ti-10Mo-6Zr alloy.
