摘　　要：提出了利用钴对玻璃微珠表面进行活化的化学镀镍新工艺。玻璃微珠表面在六氨合钴(Ⅱ)溶液中对六氨合钴(Ⅱ)离子进行吸附,镀液中次亚磷酸根离子将六氨合钴(Ⅱ)离子还原成单质钴作为催化活性基底材料分布在玻璃微珠表面。通过扫描电镜、X射线能量色散谱仪和X射线衍射分析表明,利用该工艺可在玻璃微珠表面形成均匀光滑、包覆完整的非晶态镍磷镀层,同时对活化机理进行了分析研究。New activation process with cobalt in electroless nickel plating on the cenosphere surtace was proposed. [Co （NH3）612＋ were adsorbed on the cenosphere surface when the cenospheres were put into the [Co- （NH3）6]2＋ solution. [Co（NH3 ）6]2＋ were deoxidized into Co as active basic materials which spread on the cenosphere surface by the H2PO2- in the coating solution. The analysis by the SEM, EDS and XRD show that an even, smooth, integrated, amorphous Ni-P alloy layer is coated on the cenosphere surface. The mechanism of the activation was analyzed and researched.
