Abstract

Abstract: Single aluminide and Pt modified aluminide coatings were fabricated by chemical vapor deposition(CVD) on single crystal superalloy substrates, and their high-temperature oxidation and hot corrosion behaviors were investigated. The phase composition and microstructure of the two aluminide coatings were analyzed by XRD and SEM. The results indicate that both of the oxidation kinetics curves of the two aluminide coatings are in accordance with parabolic rule after oxidation at 1000℃ for 250 h. The performance of oxidation resistance of Pt-Al coating is improved 55.5 percent compared with single Al coating. The addition of Pt element can reduce the velocity of β→γ′ phase transition, further ensuring to the formation of high quality α-Al₂O₃ scale. The corrosion kinetics curves of the two aluminide coatings are also consistent with parabolic rule after hot corrosion at 900℃ for 100 h. The performance of corrosion resistance of Pt-Al coating is improved 57.9 percent as compared with that of single Al coating. The addition of Pt element can restrict the rapid germination of inner sulfuration and ensure the integrity of α-Al₂O₃ scale.
