摘要
针对A49合金制造的脱硫泵叶轮常出现的过早腐蚀失效问题,试验了不同成分的A49合金,试验表明:随着合金中Mo、Ni、Cu质量分数的增加,腐蚀电极电位增高,腐蚀电流下降,腐蚀速率下降。
The FGD pump impeller made of alloy A49 is often not available due to early corrosion.Aafter testing alloy A49 with different composition,the results show that with the increase of element Mo,Ni,Cu in alloy,the corrosion electrode potential increases, corrosion eurrent declines, corrosion rate declines.
