This study investigated the role of valence electron orbital filling ( e/a ratio) on the reported corrosion resistance performance of Ti-Pt and Ti- Au binary alloys containing less than 10 atomic percent (at. %) precious metal. The valence electron orbital filling enabled us to determine the oxidation states of these binary Ti alloys, and thus establish a correlation with corresponding corrosion performance. It is known from literature that high oxidation state results in high oxygen to metal coverage, i.e., a very stable metal-oxide layer with high oxygen to metal ratio is formed.
