| 摘 要： | 在无氧铜的基体上制备了等离子喷涂钨基涂层以应用于核聚变反应堆中偏滤器部件的面向等离子体材料。比较了不同过渡层对等离子喷涂钨基涂层结合强度的影响。采用扫描电镜和能谱分析仪对涂层的微观形貌和组成进行了观察和分析。发现在涂层中和铜结合的界面比较疏松，而和钨结合的界面则较为致密。拉伸试验结果表明，和其他样品相比，室温下没有过渡层的钨涂层界面表现出较高的结合强度。

| Abstract: | The plasma sprayed tungsten coatings were prepared on oxygen free copper substrates, which are to be used as the plasma-facing materials of the divergent components in fusion reactors. The influences of different interlayers on bonding strengths of the plasma-sprayed tungsten coatings were compared. The morphologies and compositions of the coatings were observed and analysed by SEM, EDS. It was found that the bond between copper and the coating was relatively loose, and the bond between tungsten and the coating was relatively dense. Tensile tests indicated that the tungsten coating without any interlayer showed higher bonding strength than that of the other specimens. |
