    摘要:

    采用大氣等離子噴涂技術(shù)(APS)在C/C復(fù)合材料表面制備了mullite/ZrB2-MoSi2雙層抗燒蝕涂層。借助XRD、SEM、EDS等分析手段對涂層的組織結(jié)構(gòu)進(jìn)行研究；基于氧丙烯焰燒蝕試驗考察ZrB2-MoSi2/mullite復(fù)合涂層對C/C復(fù)合材料高溫耐燒蝕性能的影響。結(jié)果表明,在1700 °C和1800 °C的氧丙烯焰下燒蝕60 s,ZrB2-MoSi2/mullite涂層試樣的質(zhì)量燒蝕率分別為3.49×10-3 g/s與3.77×10-3 g/s。其與單層ZrB2-MoSi2涂層試樣相比,ZrB2-MoSi2/mullite涂層試樣展現(xiàn)了出色的抗燒蝕性能。燒蝕過程中形成的硅酸鹽玻璃可以作為熱障層而減少氧氣的進(jìn)一步滲透,并且還具有自我封填缺陷的能力,使ZrB2-MoSi2/mullite涂層表現(xiàn)較好的抗燒蝕性。

    Abstract:

    Mullite/ZrB2-MoSi2 coating was deposited on carbon/carbon(C/C) composites to protect against ablation by atmospheric plasma spraying (APS). The microstructure and morphology of the coating were characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. The ablation resistance of the coating was investigated at different temperatures with oxypropylene torch. The mass ablation rates of the Mullite/ZrB2-MoSi2 coated C/C composites were 3.49×10-3 g/s and 3.77×10-3 g/s after ablation at 1700 °C and 1800 °C for 60 s respectively, which exhibited good ablation resistance compared with the single-layer ZrB2-MoSi2 coated. The increase of ablation resistance can be attributed to the formation of a silicates glass film, which acted as thermal barrier and self-sealed the defects of the coatings.
