中文摘要：

为了制备可以在磁场中悬浮的ICF（惯性约束聚变）靶丸，采用化学镀法对空心PS靶丸包覆Ni-P合金磁性镀层。化学镀Ni-P合金工艺条件为：NiSO4·6H2O为30g／L，NaH2PO2为30g／L，焦磷酸钠为60g／L，pH值为10.5，温度为40℃。采用SEM、DSC、VSM分析镀层结构、形貌以及磁性，结果表明：Ni—P镀层在PS微球表面沉积均匀，表面光滑；微球的饱和磁化强度为1．074×10^-2emu，所具有的磁性可使其在磁场中悬浮。

英文摘要：

For the purpose of magnetic targets that can be suspended in magnetic field used for ICF, a chemical plating method was adopted to prepare such magnetic targets with Ni-P magnetic layers. The optimal experiment parameters as below： NiSO4 · 6H2O was 30g/L, NaH2PO2 was 30g/L, sodium pyrophosphate was 60g/L, pH value was 10. 5 and the temperature was 40℃ SEM, DSC and VSM etc modern testing methods were respectively used to measure the structure, the morphology and magnetism of as-prepared samples. These studies indicated that the saturated magnetism of PS targets with smooth Ni-P layers on surface was 1. 074;〈 10^-2emu, which was enough for PS targets to suspend in magnetic field.
