摘要
通过电化学试验、盐雾加速试验和全浸加速腐蚀试验,在模拟海洋性大气腐蚀环境和工业与重污染大气腐蚀环境条件下,研究了不同化学组成的钢基表面热镀Zn-Mg合金镀层的腐蚀行为。三种试验方法研究结果表明,该镀层无论在海洋性大气腐蚀环境还是工业和重污染大气腐蚀环境条件下均表现出一致性的优良耐蚀性能;就实际工业生产而言,研究结果认为Zn-Mg合金镁含量控制在1%-2%的范围内是适宜的。
Using electrochemistry experiment, salt spray tests and accelerated corrosion experiment, under the ocean atmospheric corrosion and the polluted air corrosion environment, the corrosion behavior of different composition of hot-dip Zn-Mg alloy coated steel sheet was studied. It was found that the Zn-Mg alloy coated steel sheet has excellent corrosion resistance both under the ocean atmos-pheric corrosion and the polluted air corrosion environment. But in the production, the preferable Mg content is 1%-2%.
