Tribological properties of oxidized ZrNb7, exposed to three different heat treatment routes, were investigated. These are: oxidation in air, a three stepand an oxidation at low . The latter two increase the oxygen below the leading to enhanced coating adhesion. To assess tribological properties, a self-developed knee test bench was used where all three variants of ZrNb7 were compared to commercially available materials. ZrNb7 oxidized at low oxygen partial pressure shows the lowest wear, both on the ceramic surface and on the counterpart. In addition, the same coating exhibits better performance in Calo wear tests than the surface of martensitic hardened steel (100Cr6) as a reference material.
