摘要(Abstract)：

采用真空电弧熔炼制备了CrCoNi与(CrCoNi)_(96)Cu_4中熵合金，首先对合金进行了变形量为67%的轧制变形，随后在800℃下进行退火30 min的处理，比较退火态CrCoNi与(CrCoNi)_(96)Cu_4中熵合金在0.5 mol/L H_2SO_4溶液中的腐蚀行为。通过X射线衍射(XRD)、扫描电镜(SEM)、原子力显微镜(AFM)对合金的相结构及腐蚀后的微观组织进行表征，利用动电位极化曲线与交流阻抗(EIS)对合金在0.5 mol/L H_2SO_4溶液中的腐蚀性能进行测试。结果表明：在0.5 mol/L H_2SO_4溶液中，(CrCoNi)_(96)Cu_4合金的自腐蚀电流密度与腐蚀速率均小于CrCoNi合金；EIS数据表明(CrCoNi)_(96)Cu_4合金的钝化膜电阻大于CrCoNi合金的钝化膜电阻，即(CrCoNi)_(96)Cu_4合金比CrCoNi合金具有更为优异的耐腐蚀性能。
