摘　　要：研究了Ni-Cu-P钢、含铜量相对低的合金钢和普通碳钢在海水中的腐蚀行为。结果表明,铜元素能够减缓合金的腐蚀速率,所以Ni-Cu-P钢的耐腐蚀性能最好。Ni-Cu-P钢的组织更为密实,这是因为其蚀坑中有铜元素的富集。The corrosion behaviors of the steel Ni-Cu-P, relatively low amount of copper alloy steel and common carbon steel were investigated. The results show that the element Cu can slow down the corrosion rate of the alloy, and thus the corrosion resistance of the steel Ni-Cu-P is best. The microstructure of the steel Ni-Cu-P is more dense, which is due to the enrichment of the element Cu in the etch pit.
