Rezumat

The cellular response of anodically treated titanium alloys was investigated using cell attachment, morphological and surface analytical techniques. The behavior of a β Ti15Mo alloy has been compared with the conventional mixed alloy, Ti6Al4V and the α alloy, Ti2. Ti15Mo β alloy demonstrated a higher cell count and a thicker oxide on its surface. The presence of Ca and P was detected in all the alloys after the invitro cell culture test. TiO2 was present as the dominant oxide in all three alloys.
