摘　　要：为研究Al⁃Zn⁃In⁃Sn⁃Mg系五元铝基牺牲阳极材料在油田采出水中的性能,熔炼了4组不同合金含量的Al⁃Zn⁃In⁃Sn⁃Mg系铝基牺牲阳极材料,测试了4组牺牲阳极材料在采出水环境下的开路电位、电流效率、腐蚀均匀性以及腐蚀产物的黏附情况。用金相显微镜、扫描电镜和能谱观察材料的组织、第二相形态以及合金元素的分布情况;通过动电位极化曲线、电化学阻抗谱和加速腐蚀试验,最终筛选出了4组阳极试样中性能最好的阳极材料,并根据电化学测试结果分析了合金材料在采出水中的活化机理。In order to study the performance of Al⁃Zn⁃In⁃Sn⁃Mg quinary aluminum⁃based sacrificial anode materials in oilfield produced water,four sets of Al⁃Zn⁃In⁃Sn⁃Mg quinary aluminum⁃based sacrificial anode materials with different alloy compositions were melted.The open⁃circuit potential,current efficiency,corrosion uniformity and adhesion of corrosion products of the four sacrificial anode materials were tested in the produced water environment.The microstructure,second⁃phase morphology and distribution of alloy elements were observed using metallographic microscopy,scanning electron microscopy(SEM)and energy⁃dispersive spectroscopy(EDS).Through potentiodynamic polarization curves,electrochemical impedance spectroscopy(EIS)and accelerated corrosion tests,the anode material with best performance was selected from the four sets of anode samples.Based on the electrochemical test results,the activation mechanism of the alloy materials in produced water was analyzed.
