| 摘 要： | 为研究水分在粘接接头界面的扩散行为，采用X射线能谱（EDX）分析方法计算了水分在碳／碳复合材料粘接接头界面的扩散系数和扩散动力学，并比较了水分在不同表面处理方法处理的碳／碳复合材料粘接接头界面的扩散系数和扩散动力学．结果表明，经偶联剂处理的碳／碳复合材料耐久性能要好于化学氧化和砂纸打磨处理，这与剪切强度测试结果相一致．

| Abstract: | EDX analysis method was used to measure the width of adhesive/c - c composites joints interface and its elements content, so the water diffusion coefficient and dynamics in adhesive/c - c composites joints can be calculated. Water diffusion coefficient and dynamics of adhesive/c - c composites joints treated by different surface treatment methods were also researched in this paper. Results indicated that the water diffusion speed in adhesive/c - c composites joints treated by sand paper was faster than that treated by chemical oxidation and by silane couple agent treatment. |
