摘　　要：采用旋转圆盘法对907A、921A钢在含有0．3％石英砂（200～300目）的3．5％NaCl溶液中的冲刷腐蚀和磨蚀性能分别进行测试，用失重法评价了2种材料的抗冲刷腐蚀和磨蚀性能，并利用扫描电镜观察了其腐蚀形貌．结果表明，921A钢在3．5％的NaCl溶液中的抗冲刷腐蚀性能及抗磨蚀性能均高于907A钢．Erosion and cavitation-abrasion behavior of 907A and 921A steels in 3.5 96 NaCl aqueous solution with quartz sand was studied by rotating disc equipment. The resistance to erosion and cavitation-abrasion of the two steels were evaluated by mass-loss method, and corrosion surface morphologies were observed by SEM. The results showed that 921A steel has better resistance to erosion and cavitation-abrasion than 907A steels.
