Abstract
Hip replacement stems manufactured from Ti6Al4V titanium alloy were su rface treated in one of four ways and tested for dissolution resistanc e in bovine serum. Those stems treated thermally were found to have si gnificantly lower metal ion release corn pared with those receiving st andard commercial treatments. The improved dissolution behaviour is as sociated with a change in the surface oxide structure from mixed titan ium oxides to a more stable rutile structure.
