Abstract：In order to improve the heat resistance of carbon fiber reinforced resin matrix composites, Ni/NiCrAlY/8YSZ(ZrO2 – 8%Y2O3) composite coatings were prepared on cyanate ester resin-based carbon fiber substrate by plasma spraying, and the phase composition and microstructure of the coatings were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The heat resistance of Ni/NiCrAlY/8YSZ composite coating was studied
by using the ablation resistance test. The results show that the Ni/NiCrAlY/8YSZ composite coating prepared by plasma spraying has a compact structure, and there are no obvious defects such as interlaminar gaps and pores, and the composite coating can protect the substrate well after the ablation test, and at 1000 ℃, the pores are generated inside the coating, but it is tightly combined with the substrate, and the interface is not damaged.
