摘　　要：采用熔炼法制备稀土系储氢合金及Co-B合金.研究了稀土系储氢合金的添加对Co-B合金的结构以及储氢性能的影响.结果表明添加稀土合金后,Co-B合金的电化学容量和抗腐蚀性能有了较大的提高.The rare earth alloys and the Co-B alloy were prepared by melting, and the the rare alloys were added to the Co-B alloy. The effect of the added rare earth alloys on the hydrogen storage performance of the Co-B alloy was researched. The research results showed that after added the rare earth alloys, the hydrogen storage performance and the anticorrosion performance were improved greatly.
