摘要: 随着航空发动机的日益发展,燃烧室火焰温度的不断提高,广泛应用于航空发动机冷端部件的树脂基复合材料面临着更加严苛的氧化烧蚀环境,而在树脂基复合材料表面制备抗氧化烧蚀涂层则是一种有效可行的应对策略。在各类涂层方案及体系中,兼具隔热、抗氧化、应力缓冲等特点的多层结构体系受到广泛关注,该研究提出Al/NiCoCrAl/YSZ三层结构涂层,并使用酚醛树脂和SiO2对YSZ进行改性,利用喷雾造粒的方法对改性后的复合粉体进行制备,使用大气等离子喷涂方法在碳纤维增强的聚酰亚胺基复合材料表面制备涂层样品。在热流密度为100 J/(m2·s)的氧乙炔燃流条件下,酚醛树脂含量为6wt.%改性的涂层的防护效果最佳,试样的线烧蚀率为4.42×10-4 mm/s,质量烧蚀率为9×10-6 g/s。

Abstract: With the increasing development of aviation engines and the continuous increase of combustion chamber flame temperature, resin based composite materials widely used in cold end components of aviation engines face more severe oxidation and ablation environments. Preparing anti oxidation and ablation coatings on the surface of resin based composite materials is an effective and feasible response strategy. Among various coating schemes and systems, the multi-layer structure system with the characteristics of heat insulation, oxidation resistance, stress buffering, etc. has attracted wide attention. In this study, Al/NiCoCrAl/YSZ three-layer structure coating is proposed, and YSZ is modified by phenolic resin and SiO2, the modified composite powder is prepared by spray granulation, and coating samples are prepared on the surface of carbon fiber reinforced polyimide matrix composites by atmospheric plasma spraying. Under ablation conditions of oxyacetylene combustion with a heat flux density of 100 J/(m2·s), the modified coating with a phenolic resin content of 6wt.% has the best protective effect. The line ablation rate and mass ablation rate of the sample are 4.42×10-4 mm/s and 9×10-6 g/s, respectively.
