【摘要】 应用电化学方法对Pb Ca合金和Pb Sb Cd合金在硫酸溶液中的导电性、析气性和耐腐蚀性等进行研究。结果显示Pb Sb Cd合金有好的导电性和低的析气性,其中,析氢电位相对于铅钙合金提高了60mV,析氧电流降低近2/3,但耐腐蚀性能有待进一步提高,并提出了新方案设想。更多还原

【Abstract】 The conductivity,corrosion resistance and gas evolution of PbCa and PbSbCd alloys under constant concentration of H2SO4 were studied using electrochemical techniques.Compared with PbCa alloy,PbSbCd alloy had favorable performance in conductivity and gas evolution,hydrogenovervoltage in PbSbCd alloy cathode was increased by 60?mV compared with PbCa alloy,but its corrosionresistance was unsatisfied.A new idea was assumed.更多还原
