以铬酸-浓硫酸表面处理后的打印碳粉为基体，一定条件下水合肼与硫酸镍形成的[Ni(N2 H4)3]2＋吸附在碳粉表面还原成均匀的镍单质层，得到镀镍打印碳粉微球.采用XRD、TGA、SEM和EDS等对镍晶相、镍含量、镍层厚度以及组成进行了分析和表征.结果表明：碳粉表面有效地包覆一层厚度约2μm、均匀致密、立方相多角的镍单质层，镍含量为44．5％.
Under a certain condition [Ni(N2 H4 )3 ]2+ was formed by the reaction of the hydrazine hydrate with nickel sulfate.The nickel-coated toner was prepared by the redox reaction of [Ni(N2 H4 )3 ]2+ on the surface of the toner coarsened by chromic acid concentrated sulfuric acid.XRD,TGA,SEM and EDS measurements were used to characterize the crystalline phase,morphologies,thickness and content of nickel layer for the nickel-coated toner.The results showed the toner was uniformly coated by 2μm thick nickel,which belonged to the multangular cubic phase,and the nickel content was 44.5%.
