Abstract
The hot corrosion behavior of titanium alloy and AlCuFeCr quasicrystalline coating on titanium alloy in the presence of a solid NaCl deposit at 650, 700 and 750 °C was studied. The result shows that weight-gain kinetics for titanium alloy exhibited a linear rate law, while the kinetics for AlCuFeCr quasicrystalline coating displayed parabolic growth rate. The corrosion resistance of the titanium alloy was improved by applying the AlCuFeCr quasicrystalline coating. The corrosive oxide morphology formed on titanium alloy was porous. For AlCuFeCr quasicrystalline coating with NaCl deposit, the scale formed on the coating surface was compact and uniform. Oxide formed on the surfaces of Al–Cu–Fe–Cr quasicrystalline coatings after hot corrosion consisted of Al2O3.
