摘要
通过等离子体源离子注入法(PSII),对带有SiC涂层的C纤维增强SiC基(SiCC/SiC)复合材料进行硼离子注入,研究了硼离子注入对样品抗氧化性能的影响。通过俄歇电子能谱检测分析了样品成份的深度分布。在空气中1300℃的高温条件下进行了氧化实验。通过XRD和扫描电镜分别对样品的化学组成和表面形貌进行了表征,对样品的力学性能进行了测试。结果表明,对SiCC/SiC复合材料注入硼有助于提高其抗氧化性能。经过离子注入试样的弯曲性能与未经离子注入试样相比变化很小。
CVD-SiC coated C/SiC composites were implanted with boron ions by plasma source ion implantation to improve its oxidation resistance. Depth profile of the boron ions in the boron-implanted SiC-C/SiC composites was checked by Auger electronic energy spectrum. Oxidation tests of the SiC-C/SiC composites were performed in flowing dry air at 1300°C. The sample with boron ion implantation exhibits lower mass loss than those without boron ion implantation. The surface morphology of the sample was obtained by scan electronic microscope. Some air bubbles were observed in the coating. Flexural strength tests show that the mechanical property of ion-implanted samples changes little compared with that of the samples without ion implantation.
