RESISTANCE TO EROSION AND CAVITATION - ABRASION OF STEELS 907A AND 921A IN 3.5%NaCl SOLUTION WITH SAND
907A、921A钢的抗冲刷腐蚀和磨蚀性能

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.
