摘要
采用单因素试验化选法，研究了以铈为主的轻混合稀土的含量变化（含量变化范围的质量分数为0％～0．5％）对Zn－0．5％Pb合金性能的影响，并与XD2合金的性能进行了比较．试验结果表明：当混合稀土的添加量为0．07％～0．2％时，Zn－0．5％Ph－RE合金的抗拉强度与XD2合金的基本相同，冲压性能略低，但耐均匀腐蚀性能比XD2合金优越，延伸率高7％，代替XD2合金作干电池的负极材料，能延长干电池的使用寿命．
By optimum seeking method of single factor, the influnce of the content of light mixed RE,mainly of Ce (weight percentage ranging from ON to 0' 5% ), on the property of alloy Zn－ 0. 5 NPb is studied－ The property of the alloy is compared with that of alloy XD,. The results show that when 0. 07 % ~0. 2 %of mixed RE is added' the strength of alloy Zn－0. 5% Pb－RE, compared with alloy XD2, is roughly the same, the stamping property is a little lower, the even corrosion resistance is stronger, the specific elongation is 7% higher. The life of the cells with the alloy being negative shell can be lengthened, in place of XD2.
