摘要
对不同钒含量的机械外壳镁合金试样进行了显微组织、耐磨损性能和耐腐蚀性能的测试与分析。结果表明:随钒含量从0增加至0.7%,试样的晶粒得到细化,磨损体积先减小后增大,腐蚀电位先正移后负移,耐磨损性能和耐腐蚀性能先提升后下降。机械外壳镁合金的钒含量优选为:0.5%。
The microstructure,wear and corrosion resistance of magnesium alloy shell with different vanadium content were tested and analyzed.The results show that with increasing vanadium content from 0 to 0.7% of the sample,the grains are refined,and the wear volume decreases firstly and then increases.Meanwhile,the corrosion potential of the sample shifts in positive direction first and then in negative direction,with both of the wear resistance and corrosion resistance increasing first and then decreasing. The optimized vanadium content is 0.5% for the magnesium alloy shell.
