Abstract
Ti-1.25% Al-0.75% Mo-1% Zr base alloy was prepared with a lower weight percentage then the standard alloy. The other 3 alloys were worked after adding the Chromium (Cr) and Nickel (Ni) elements separately and collecting them together to the base alloy using powder metallurgy technique. The corrosion tests of the alloys were carried out with Saliva and Hanks solutions, also, the hardness tests, X-ray, microstructure through using Scaning Electron Microscopy (SEM) Light Optical Microscopy (LOM) and Atomic Force Microscopy (AFM). The outcomes was showed that the addition of the chromium element improved resistance to corrosion for both solutions by 28% Saliva and 40% Hanks for base alloy. Also, the combination of the 2 elements gives higher improvement corrosion resistance via., compared with the base alloy and addition nickel alone. Moreover, the results of microstructure was indicated that the increased of β phase of Ti-1.25% Al-0.75% Mo-1% Zr-0.5% Cr alloys while the hardness results were showed increasing with addition elements, X-ray indicated that new phases. As well the nature of corroded surfaces had a little different from the uncorroded during the tests of the atomic force microscopy for most used alloys studied.
