An investigation of wear and bioconductivity characteristics of oxidized Ti-29Nb-13Ta4.6Zr is presented. Experimental results showed that oxidation treatment at 400degreesC for 24h in air results in the formation of a hard layer on the surface of the alloy, which greatly benefits its wear resistance. Calcium phosphate (Ca-P) phase was found to grow on the oxidized and alkali treated Ti-29Nb-13Ta-4.6Zr alloy samples when they were immersed in a protein-free simulated body fluid or fast calcification solution.
