Thinking about this perhaps the Titanium gold would be a surface layer or coating over Titanium. No doubt there would be metallurgical issues with this. Funnily I had a pre-student job in a coatings company using detonation guns to fire tungsten carbide into metals in order to make them tougher. Could a similar treatment be used for Titanium hip replacements?
