This paper presents tribological results elaborated under unlubricated conditions at room temperature, 400 deg C 600 deg C and 800 deg C in the range of 0,1 m/s to 7,5 m/s with two distinct different, non-commercial and novel metallurgical concepts based on Magneli-type phases displaying wear rates, which are one to two orders of magnitude below those published for NASA PS30x-coatings: (1) (Ti,Mo)(C,N) grades as monolithic materials and thermal sprayed coatings forming Magneli-type phases by tribooxidation and (2) Ti(n-2)Cr2O(2n-1), Magneli-phases of titanic stabilized by chromium as thermal sprayed coatings resulting in oxidation resistant Magneli-phases. The established wear rates qualify both metallurgical concepts for radial and axial air foil bearings in small jet turbines and turbochargers, but are not limited to these, as well as the values of wear rates are comparable to those typically attributed under mixed/boundary lubrication of liquid lubricated tribosystems.
