Abstract
- The high-temperature oxidation behavior of titanium-based alloys coated with Al–Cu–Fe–Cr quasicrystal using the low-pressure plasma spraying (LPPS) method was studied. The results showed that Al–Cu–Fe–Cr quasicrystal line coating improved the oxidation resistance of titanium-based alloys. The weight gains at 750 and 800 °C for Al–Cu–Fe–Cr quasicrystalline coating are very low and the oxidation kinetics follows a parabolic law. During the oxidation period there is no evident spallation of the coating from the substrate. Oxide formed on the surface of Al–Cu–Fe–Cr quasicrystalline coating after oxidation consisted of Al2O3.
