摘要
以胶态钯为活化液对空心玻璃微珠表面化学镀镍工艺进行了研究。通过环境扫描电镜(ESEM)和能谱分析(EDS)分别对微珠镀镍前后的形貌进行了观察、对镀层成分进行了测试,并对微珠施镀装置进行了设计。结果表明:利用该工艺可在微珠表面形成光滑、均匀的N i-P镀层,且在微珠间无散落的镀层金属颗粒存在;采用液体搅拌促进镀液循环,有利于微珠的悬浮和分散,并提高镀液的稳定性,为空心玻璃微珠表面的金属化提供了一个简单易行的工艺。
The technique for the cenosphere particles modified by electroless nickel plating with pallamine activation was investigated. The morphologies of original and modified eenospheres particles were checked by environment scanning electron microscope （ESEM） , and the composition of original and electroless nickel plated cenosphere surfaces were determined by energy dispersive X ray spectroscopy （ EDS）. The plating device of cenospheres was also designed. The results show that uniform and continuous Ni-P alloy coating is obtained under the given coating conditions. Circle pump can stir plating solution adequately and be propitious for suspension and dispersion of cenospheres. A simple technique for the cenospheres modified by metal plating was suggested.
