Description
Technical Field
The invention belongs to a coating preparation technology, and relates to a long-time oxidation-resistant ZrSi on the surface of a C/C composite material2-Y2O3a/SiC composite coating and a preparation method thereof.
Background
The C/C composite material has excellent mechanical property and is the most ideal high-temperature thermal structure material, but the application range of the C/C composite material is limited by the problem that the C/C composite material is easy to oxidize in a high-temperature aerobic environment, and the C/C composite material is the most effective method by adopting an external coating technology. SAPS technology is one of the methods for efficiently preparing coatings developed in recent years, the plasma arc temperature of the SAPS technology can reach 10000 ℃, and ultrahigh and high melting point can be preparedThe ceramic coating and the prepared coating have high interfacial bonding force, but the prepared coating has a small amount of cracks and pores. The external coating is mainly glass phase SiO generated by silicon-based phase ceramic oxidation at high temperature2Capable of healing coating microcracks and micropores to improve oxidation performance, but glassy phase SiO2Volatilization occurs at 1500 ℃, and cracks in the coating can propagate at high temperature to produce SiO2The glass phase is limited and does not heal all of the microcracks and pores of the coating, thereby providing a pathway for oxygen, ultimately leading to failure of the coating's oxidative properties. The oxidation resistance of the oxidation resistant coating prepared by the SAPS method at present is still not ideal at 1500 ℃.
The document 1 "A ZrB 2-SiC/SiC oxidation protective double-layer coating for carbon/carbon composites, Shanbao Zhou, Yushi Qi, Peng Wang, Yehong Cheng and Wenbo Han, Advances in Applied Ceramics,2017: 1-6" indicates that the ZrB2-SiC coating has an oxidation time of 18h at 1500 ℃ and that the coating loses 1.8% weight, and the oxidation product SiO generated in the coating is SiO2One part is volatilized, the other part and an oxidation product ZrO2React to generate ZrSiO4,ZrSiO4Can effectively improve the oxidation resistance of the coating, but because of the SiO of the coating2The content is continuously reduced, and cracks and pores generated in the final coating are difficult to heal, so that the coating fails.
Document 2 "Oxidation resistance of a La-Mo-Si-O-C coating prepared by Supersonic atomic Plasma Spraying on the Surface of SiC-coated C/C compositions, Xiaohong Shi, Changcong Wang, Hongjiao Lin, Caixia Huo, Xiuxiu Jin, Guoge Shi, Kaiyan Dong, Surface & Coatings Technology,2016,300: 10-18" indicates that the coating Oxidation system prepared by the SAPA method has a certain Oxidation resistance, static Oxidation 85h at 1500 ℃ is 5.12%, and the failure reason is mainly due to the fact that the non-healing cracks and pores in the coating provide channels for oxygen, resulting in a shorter Oxidation time.
Therefore, the preparation of the C/C composite material oxidation resistant coating by the SAPS method for a long time is a problem which is difficult to break through.
