ICF玻璃靶丸化学镀磁性Ni-P涂层的研究

 采用化学镀方法对ICF空心玻璃微球靶丸进行处理，使其表面均匀包覆一层磁性Ni-P合金镀层，从而使得ICF玻璃靶丸具有一定的磁性，可望用于进行磁悬浮ICF定位打靶实验研究。用X射线衍射仪、扫描电子显微镜和振动样品磁强计对涂层的组成、结构、形貌及磁性能进行了表征。结果表明：对 ICF玻璃靶丸进行化学镀处理，其球形度、同心度和壁厚均匀性都与化学镀前未发生明显改变，其饱和磁化强度和矫顽力分别为3.883×10^-3 A/g和1.046×^-3 T。

Magnetic Ni-P plating on ICF glass targets

ICF glass targets were treated by electroless plating technology.Magnetic Ni-P coatings cover the surface of ICF glass targets,so the plated ICF glass targets are magnetic and could be used in research of magnetic suspension experiment.The composition,structure,morphology and the magnetic property of the Ni-P coated ICF targets were analyzed by X-ray diffraction,scanning electron microscopy and vibrating sample magnetometer.The results show that the global degree,the homocentric degree and the mural uniformity of the plated ICF glass targets were nearly the same as those of the ICF glass targets before plating.However,the surface smoothness of plated ICF glass targets is worse.
