随着国家双碳战略的提出，析氢材料越来越受到关注。为了研究电沉积合金材料的析氢性能，本文在离子液体中通过脉冲电沉积法在碳钢上制备钴铬合金，研究了离子液体中电沉积不同的钴盐浓度对析氢过电位的影响，并与离子液体中电沉积的Co电极和Cr电极，水溶液中电沉积的Co-Cr合金电极进行了对比分析。利用三电极体系测试沉积电极在碱性环境下的电化学性能，采用线性极化法、方波电位法、交流阻抗法、恒电流电解法等电化学测试方法，并结合XRD、SEM、EDS进行了形貌、物相与元素分析。实验结果表明: 制备的Co-Cr合金是多晶的，其晶粒尺寸为12.3 nm；当电流密度为10和100 mA/cm2时，所对应析氢过电位...
