摘要通过对 SiC 纤维增强 Ti6Al4V 复合材料的拉伸试件断口与界面观察，研究了 SiC 纤维 C 涂层对基体与纤维元素扩散、界面反应层厚度与成分、拉伸断口的影响。结果表明，与纤维无 C 涂层的 SiC f /Ti6Al4V相比较，有纤维 C 涂层的 SiC f /Ti6Al4V 界面结合强度较弱、反应层厚度较厚，涂层能有效防止纤维性能在复合过程中下降，提高了复合材料拉伸强度。
Abstract：The fracture profi le and interface of SiC fi ber reinforced Ti6Al4V (SiC f /Ti6Al4V) are analyzed, the infl uence of C coating on the inter-diffusion between fiber and matrix, the thickness and composition of reaction layer, tensile fracture profi le is researched. It indicates that SiC f /Ti6Al4V composites made of C coated fi ber has a weaker interface and a thicker reaction layer comparing with uncoated fi ber, the coating can prevent the fi ber mechanical properties from decreasing during the consolidation process, and a high tensile strength is achieved.
