观察了电沉积法制备泡沫Ｎｉ过程中各阶段的Ｎｉ层组织形态变化，结果表明：电镀后和６００℃空气处理４ｍｉｎ后的Ｎｉ层均为细晶组织，但经８５０℃和９８０℃的氢分解气氛处理４０ｍｉｎ后，均达到充分烧结，泡沫Ｎｉ表面平整致密，由大晶粒多晶Ｎｉ组成
The morphologies of the Ni layer in each phase of the foamed Ni electrodeposited by electrodeposition were observed. The results showed that the Ni layer was fine-grained after the electroplating and the air treatment at 600 ℃ for 4min. However, after hydrogen decomposition at 850 ℃ and 980 ℃, Atmospheric treatment 40min, have reached full sintering, foam Ni surface smooth and dense, composed of large-grained polycrystalline Ni
