形变对CuZnAl合金在3.5%NaCl溶液中腐蚀性能的影响

Effect of Deformation on Corrosion Resistance of CuZnAl Alloy in 3.5% NaCl Solution

通过对不同状态下的CuZnAl合金在3.5%NaCl溶液中腐蚀速率的测定,分析形变对该合金腐蚀性能的影响。结果表明:形变能降低合金的腐蚀性能,形变后经再结晶退火,能使变形态合金的腐蚀性能有所提高,但仍低于未变形退火态。

The effect of deformation on corrosion resistance of CuZnAl alloy in 3.% NaCl solution was analyzed by measuring corrosion rate in different state. The results show that deformation makes the corrosion resistance decrease, recrystallization annealing after deformation makes corrosion resistance of deformation state increase, but the corrosion resistance is lower than that in undeformed state.
