Experiments of erosion corrosion with 3.5% NaCl solution at different flow rates were performed for TP2 copper after different heat treatment (hard and soft states), and the erosion corrosion rates of TP2 copper were tested. The morphology and products after 240 hours of corrosion were characterized, and the mechanism of erosion and corrosion for TP2 copper was also discussed. The results show that flowing medium in corrosion test accelerates the corrosion rate of TP2 copper. The soft TP2 copper presents a higher corrosion rate, compared to hard TP2 copper, after 240 hours of corrosion at the same flow rate. And after 240 hours of erosion corrosion at a higher flow rate, TP2 copper has its surface morphology predominated by gully-like structure and a product of Cu2O is generated after corrosion.
