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 behavior of Ni-Cu-P steel, alloy steel with relatively low copper content and ordinary carbon steel in seawater was studied. The results show that copper can slow down the corrosion rate of the alloy, so the corrosion resistance of Ni-Cu-P steel is the best. The texture of Ni-Cu-P steel is denser because of the copper enrichment in the pits.
