几种典型金属材料西沙海洋全浸区腐蚀行为规律研究
|
摘要
目的研究几种典型金属材料在西沙海洋全浸区的腐蚀行为规律。方法通过外场暴露试验,分析EH36和CM690船用钢、316L不锈钢以及5083铝合金材料暴露0.5、1、2a后的腐蚀形貌与动力学规律。结果CM690腐蚀速率要大于EH36,而点蚀深度规律相反。316L不锈钢发生较为严重缝隙腐蚀,5083铝合金则以局部腐蚀为主。结论试验条件下,EH36与CM690钢腐蚀质量损失与点蚀最为严重,316L不锈钢与5083铝合金生物污损严重,伴有局部腐蚀。
Objective To investigate corrosion behaviors and rules of typical metal materials in Xisha marine immersion zone. Methods Field exposure test was carried out on marine steels of EH36 and CM690, 316 L stainless steel as well as 5083 aluminium alloy materials at Xisha for 0.5 a, 1 a and 2 a. After samples were retrieved, the corrosion morphology characteristics and kinetics rules were analyzed. Results The corrosion rate of CM690 was higher than that of EH36, while the rule was opposite for the pitting depth; serious crevice corrosion occurred on 316 L stainless steel, and it was mainly local corrosion for5083 aluminum alloy. Conclusion Under the test conditions, the corrosion weight loss and pitting corrosion of EH36 and CM690 steel are the most serious; the biofouling of 316 L stainless steel and 5083 aluminum alloy is severe, accompanied by local corrosion.
