以水合肼（N2 H4. H2O）为还原剂，采用化学镀法制备了Ni/Si 3 N4包覆粉体。用扫描电子显微镜、能谱仪、透射电子显微镜、高分辨透射电子显微镜和X射线衍射等技术对包覆粉末进行了表征，以确定其粒度、组成、相和形貌。结果表明，本方法制备的Ni/Si 3 N4复合材料具有核壳结构，Ni层在Si 3 N4颗粒表面较为连续均匀，但不可避免地只有在很小的区域内发生了Ni颗粒的聚集。原则上，涂层工艺是成功的和可预期的。
The Ni/Si3N4coated powders were successfully prepared via electroless plating method by using hydrazine hydrate (N2H4·H2O) as a reducing agent. The coated powders were characterized with several techniques such as scanning electron microscope, energy dispersive spectrometer, Transmission electron microscopy, high-resolution transmission electron microscopy and X-ray diffraction to determine particle size, composition, phase and morphology. It indicated that the core–shell structure of Ni/Si3N4has been constructed in the present method, the Ni layer on the surface of Si3N4particles was relatively continuous and uniform, but it is inevitable that only in very small area occurred the aggregation of Ni particles. In principle, the coated process was successful and expectable.
