Titanium and its alloys are widely used in biomedical devices and components, as hard tissue replacements as well as in cardiovascular applications. However, not all of the clinical requirements are met, so surface modification is often required. University of Queensland researchers have developed HardTi - novel methods for modifying the surface of titanium alloys, leading to a significant improvement in the properties that make titanium ideal for biomedical needs, as well as aerospace, consumer electronics and motor sports applications. HardTi's surface coating and gas nitriding methods overcome key problems with existing titanium alloy surface properties.
