采用tacl5 - ar - c3h6体系等温化学气相沉积方法，在碳/碳（C/C）复合材料上制备了杂化、（200）和（220）织构的TaC涂层。利用拉曼光谱、纳米压痕和氧乙炔火焰烧蚀仪分别表征了不同涂层的残余应力、硬度和烧蚀行为。结果表明：TaC涂层中存在拉应力，当织构取向由杂化变为（220）和（200）时，拉伸应力增大，涂层的纳米压痕硬度也有相同的变化趋势。沉积涂层能有效提高C/C复合材料的耐烧蚀性能。织构结构对涂层的烧蚀性能和烧蚀形貌也有很大的影响。当织构结构由杂化取向转变为（200）和（220）取向时，质量烧蚀率明显降低。杂化取向和（200）织构涂层表现为粗糙的氧化形貌，存在坑状或破损；而（220）织构涂层呈现致密的熔融氧化物形态。杂化、（200）和（220）织构TaC涂层的主要烧蚀行为分别为氧化和颗粒剥蚀和块状剥蚀、氧化和块状剥蚀、氧化和机械侵蚀和块状剥蚀。
TaC coatings with hybrid, (200) and (220) texture structure were prepared on carbon/carbon (C/C) composites by isothermal chemical vapor deposition with TaCl5–Ar–C3H6system. The residual stress, hardness and ablation behaviors of the different coatings were characterized by Raman spectra, nano-indentation and oxyacetylene flame ablation machine respectively. Results shown tensile stress exists in the TaC coatings and increases when texture orientation turns from hybrid to (220) and (200), while nano-indentation hardness of the coatings also obeys the same trend. The deposited coatings could improve the ablation-resistance properties of C/C composites effectively. The texture structure also had great effects on the ablation properties and ablation morphologies of the coatings. The mass ablation rate obviously decreases when the texture structure changes from hybrid orientation to (200) and (220) orientations. The hybrid orientation and (200) texture coatings exhibit coarse oxide morphologies with crater or some breakage existed; while the (220) texture coating shows dense, molten oxide morphology. The main ablation behaviors of the hybrid, (200) and (220) texture TaC coatings are oxidation and particle denudation and block denudation, oxidation and block denudation, oxidation and mechanical erosion and block denudation, respectively.
