Good tribological properties and low coefficient of friction have previously been reported for thermally sprayed quasicrystalline coatings. In this paper HVOF spray parameter optimization and tribological properties of quasicrystalline coatings, manufactured from three different compositions, is discussed. On-line diagnostics measurements and splat studies were performed to optimize spray parameters of HVOF. Quasicrystalline coatings were produced and the coating microstructure was analysed. Large amount of wear and friction tests were performed to determine the tribological properties of quasicrystalline coating. Relatively high values of the coefficient of friction were obtained in the PoD-test. These tests yielded friction values varying typically between 0.4–0.6 independent of the counter material.
