Titanium and its alloys are very useful nowadays, due to its sorcerous properties of high strength to weight ratio, high corrosive resistance, and biocompatibility; it is substantive as god metal. In the presented work the anodic film formation and variation in the aesthetic appearance of anodized titanium titanium-strontium oxide composite alloy surface are investigated at certain levels of the applied potential difference across both terminal ends in an electrochemical circuit using sulfuric acid as an electrolyte. This paper focuses on recent developments of new anodized commercially pure titanium -strontium oxide composite alloy, where additions of strontium oxide were prepared specific percentage (6%) by wt.% for biomedical applications. The effect of additions of strontium oxide was investigated using SEM and EDS mapping for elemental analysis, Atomic Force Microscopy(AFM) Analysis before and after anodization, and wettability of the finished surfaces. According to the results, it is found that strontium oxide additives and anodized surfaces results increase roughness. However, in conclusion, the alloy that content at 6 wt.% strontium oxide micro particles additives relatively have high wettability for medical and dental applications. Also the titanium alloy of 6 wt.% strontium oxide micro particles additives that anodized relatively have high wettability than non-anodized ones. Increased roughness and high wettability showed that the prepared strontium oxide-cp titanium composite alloy has excellent potential for use as biomaterial, mainly in dental applications.
