摘要：

采用包埋法和水热电泳沉积法相结合的组合工艺在 C/C复合材料表面制得SiC/AlPO₄复合涂层.借助X射线衍射仪(XRD)和扫描电镜(SEM)对该复合涂层的晶相组成和显微结构进行了表征, 重点研究了AlPO₄晶相结构对复合涂层显微结构及抗氧化性能的影响. 结果表明：AlPO₄晶相结构对复合涂层的显微结构及抗氧化性能有较大的影响. 采用石英型磷酸铝(B-AlPO₄)晶相粉体所制备的涂层比较疏松, 涂层自身的内聚力较差且涂层内部存在较多缺陷, 采用磷石英型磷酸铝(T-AlPO₄)晶相粉体所制备的涂层的致密性和均匀性相比于B-AlPO₄有很大的提高, 但是表面存在一些小孔且涂层与基体间存在裂纹, 采用方石英型磷酸铝(C-AlPO₄)晶相粉体所制备的涂层最致密且无明显的裂纹, 与基体结合良好. C-AlPO₄晶相粉体所制备的涂层具有较好的抗氧化性能, 涂层试样在1500℃的空气气氛下氧化21h后失重仅为0.41wt%.

Abstract:

An SiC/AlPO₄ multilayers coating was fabricated on the carbon/carbon (C/C) composites by using the pack cementation and the hydrothermal electrophoretic deposition method. Phase compositions and microstructures of the as-prepared multi-layers coating were characterized by XRD and SEM. The influences of AlPO₄ crystalline structure on microstructure and antioxidation property of the as-prepared multi-layers coating were investigated respectively. Results show that AlPO₄ crystalline structure has strongly influence on the microstructure and antioxidation property of multi-layers coating. The porous coating with many defects is obtained using berlinite-type (B-AlPO₄) powder. Coating density and uniformity have been greatly improved by using tridymite-type AlPO₄ (T-AlPO₄) powder, but there are some small holes, and scale of cracks between the coating and the substrate can be observed. Very dense and homogeneous coating is obtained using cristobalite-type AlPO₄ (C-AlPO₄) powder. No visible micro-cracks and other defects at the interface between C-AlPO₄ coating and substrate can be observed. The C-AlPO₄ coating exhibits better antioxidation property. The as-prepared C-AlPO₄ coating could effectively protect C/C composites from oxidation at 1500℃ in air for 21h with a weight loss of 0.41wt%.
