摘　　要：利用电化学工作站、空蚀试验机、冷场发射扫描电镜和光学显微镜,研究了ZCuAl_(8)Mn_(14)Fe_(3)Ni_(2)(MAB)和B30铜合金在3.5%NaCl溶液和蒸馏水中的空泡腐蚀行为。结果表明,B30的空蚀腐蚀速率大于MAB;MAB发生了选择性相腐蚀,空泡腐蚀机理较复杂;在3.5%NaCl溶液中,MAB在中心腐蚀区、低腐蚀内环区和腐蚀外环区的孔隙率均高于B30。The cavitation corrosion behavior of ZCuAl_(8)Mn_(14)Fe_(3)Ni_(2)(MAB)and B30 copper alloys in 3.5%NaCl solution and distilled water was investigated with electrochemical workstation,cavitation test machine,field emission scanning electron microscope,and optical microscope.The results show that the cavitation mass loss rate of B30 was greater than that of MAB;selective phase corrosion occurred in MAB,and the principle of cavitation corrosion was relatively complex;in the 3.5%NaCl solution,the porosity of MAB in the central corrosion zone,low corrosion inter ring zone,and corrosion outer ring zone was higher than that of B30.
