摘　　要：研究了 4种铁铬合金在氯化钠溶液体系中的空泡腐蚀行为。重点考察了合金性能及空泡作用区相对大小对合金空蚀损失量的影响。结果表明 :合金空蚀损失量随空泡作用区与非空泡作用区表面面积比的增大而增加 ;合金的耐蚀性能和力学性能共同影响其空蚀损失量。The influence of surface galvanic effect on the behaviors of four Fe Cr alloys during cavitation damage in NaCl solution has been investigated. The results show that the galvanic effect caused by the inhomogeneity between the undamaged surface of alloy and the damaged one will be enhanced with the area ratio of the undamaged and the damaged. The behaviors of alloys during cavitation are closely related to both their mechanical performances and anti corrosion capabilities.[
