Where maximum hardness is required

If hard and scratch-resistant surfaces are required for implants and instruments made from titanium and titanium alloys, our customers use the dark anodizing process TioDark™

If hard and scratch-resistant surfaces are required for implants and instruments made from titanium and
titanium alloys, we recommend the dark anodizing process TioDark™ to our customers. This process increases the components’ fatigue-strength and reduces frictional wear. The layer created by this process shows excellent biocompatibility. TioDark™ meets the criteria for cytotoxity (ISO 10933-3/5), hemocompatibility testing (ISO-10993-4) and HET-CAM-testing (ISO 10993-4/10). Furthermore, dark anodizing prevents the release of critical alloying elements.

The dark grey color produced by the TioDark™ process is created by a combination of optical interference and absorption effects when light penetrates the oxide layers. Surface hardness, scratch-resistance and fatigue strength of the treated components are significantly increased compared to untreated components. Friction is also significantly reduced compared to other hard surfaces.
