摘要

摘要: 采用超音速等离子喷涂工艺在不锈钢基体上制备了FeAl/Al₂O₃、FeCrAl/Al₂O₃、FeAl/Al₂O₃-13%TiO₂、FeCrAl/Al₂O₃-13%TiO₂四种涂层，通过扫描电镜表征微观结构，图像分析技术测量孔隙率，多峰法计算α-Al₂O₃质量分数，并测试了涂层的抗热震性能和结合强度。结果表明：超音速等离子喷涂制备的Al₂O₃涂层中α-Al₂O₃的质量分数约为40.3%～42.5%，涂层孔隙率约为3.47%～3.52%，制备的Al₂O₃-13%TiO₂涂层中α-Al₂O₃的质量分数约为24.0%～29.7%，涂层孔隙率约为3.12%～3.31%。水淬热震实验（800 ℃/保温30 min）表明，FeCrAl/Al₂O₃涂层的抗热震性能最优，FeCrAl/Al₂O₃-13%TiO₂涂层抗热震性能次之，FeAl/Al₂O₃涂层与FeAl/Al₂O₃-13%TiO₂涂层抗热震性能最差。

Abstract: The thermal shock resistance of FeAl/Al₂O₃, FeCrAl/Al₂O₃, FeAl/Al₂O₃-13%TiO₂, and FeCrAl/Al₂O₃-13%TiO₂ coatings deposited by supersonic atmospheric plasma spraying (SAPS) on the stainless steel matrix was investigated in this paper. The microstructure of the coatings was characterized by scanning electron microscope, the porosity was measured by image analysis, the mass fraction of α-Al₂O₃ was calculated by multi peak method, and the bonding strength was tested. The results show that, the mass fraction of α-Al₂O₃ in Al₂O₃ coating is 40.3%~42.5%, the porosity is 3.47%~3.52%; the mass fraction of α-Al₂O₃ in Al₂O₃-13%TiO₂ coating is about 24.0%~29.7%, the porosity is 3.12%~3.31%. The results of water-quenching tests at 800 ℃ for 30 min show that, the FeCrAl/Al₂O₃ coating presents the highest thermal shock resistance, and the FeCrAl/Al₂O₃-13%TiO₂ coating takes the second place. The FeAl/Al₂O₃ and FeAl/Al₂O₃-13%TiO₂ coatings exhibite the same thermal shock resistance, which are the worst in four kinds of coatings.
