摘要
This study elucidated the corrosion behavior of Ti-0.3Mo-0.8Ni-2Al-xZr (x = 0, 1, 2, 3, 4 and 5 wt.%) alloys utilizing electrochemical techniques and first-principles calculation. Results revealed that the Zr addition refined the lamellar α phase, and the corrosion resistance was monotonically enhanced by increasing the Zr content. The corrosion morphologies indicated that the β phase was more susceptible to corrosion than the α phase possessing a higher Volta potential and work function. The oxide film of the surface acted as a major corrosion influence factor instead of the microstructure of the matrix in determining the corrosion performance of Ti-0.3Mo-0.8Ni-2Al-xZr alloys.
