摘要:

结合海洋平台实测的pH 值、温度、溶解氧、盐度、生物附着等数据, 通过灰色关联算法分析了海水腐蚀因子对平台钢腐蚀的影响, 并按实际影响大小进行了排序。结果表明海水腐蚀因子对于A537-1 钢和SM50B-ZC 钢平均腐蚀速率的影响主次顺序不同。对平台钢的腐蚀规律研究及现场应用提供了可参考的依据。

Grey relation analysis of steel corrosion and marine environmental factors

Abstract:

Influence of marine corrosion indicators on platform steel was studied by grey relation analysis based on in-situ measured pH, temperature, dissolved oxygen, salinity, and bio-fouling. The relation was arranged by actual effects. The results show that the influence orders of marine corrosion indicators on corrosion for A537-1 and SM50B-ZC are difference. Our results are useful to understand the corrosion behavior of marine platform steel.

Key words: grey relation analysis corrosion indicator, marine corrosion
