Notes:
The hot corrosion behavior of titanium alloy and AlCuFeCr quasicrystalline coating ontitanium alloy in the presence of a solid mixture of NaCl and Na2SO4 deposit at 700℃ was studied.The result shows that weight-gain kinetics for titanium alloy exhibited a linear rate law, while thekinetics of AlCuFeCr quasicrystalline coating displayed parabolic growth rate. The corrosionresistance of the titanium alloy was improved by applying the AlCuFeCr quasicrystalline coating. Thecorrosive oxide morphology formed on titanium alloy was porous. For AlCuFeCr quasicrystallinecoating with the mixture of NaCl and Na2SO4 deposit, the scale formed on the coating surface wascompact and uniform. Oxide formed on the surfaces of Al-Cu-Fe-Cr quasicrystalline coatings afterhot corrosion consisted of Al2O3
