磁性ICF靶丸的化学镀工艺制备与表征
Preparation and characterization of magnetic ICF target by electroless plating
-
摘要: 采用化学镀工艺在ICF聚苯乙烯靶丸表面包覆了一层磁性的Ni-P合金镀层，并分别用扫描电子显微镜、能谱仪、X射线衍射仪以及振动样品磁强计对其形貌、组成、结构和磁性能进行了表征。结果表明：通过化学镀工艺制备的Ni-P合金镀层厚度约为4 μm，且为非晶结构，并具有一定的磁性；该磁性ICF靶丸可望用来进行磁悬浮实验研究。最后，对聚苯乙烯靶丸表面磁性涂层的制备机理进行了讨论。Abstract: Magnetic ICF targets were prepared by electroless plating technology. The morphology, composition, structure and magnetic property of the magnetic ICF targets were analyzed by scanning electron microscopy, energy diffraction spectrum, X-ray diffraction and vibrating sample magnetometer. The results show that the magnetic plating is composed of Ni and P, the content of P in plating is about 7.6%, the structure of Ni-P magnetic plating is 4 μm or so, and the structure of the plated ICF targets is amorphous. The plated ICF targets can be used in magnetic suspension experiment. Furthermore, mechanism of electroless plating on ICF targets is discussed.
