摘要
通过大气腐蚀试验、室内加速腐蚀试验、电化学测试和锈层分析，研究了ＢＮＱ系列冷轧耐候钢的耐腐蚀性能。结果表明不仅有低的腐蚀率而且有好的耐蚀稳定性和适应性。并详细讨论了该钢种具有高耐候性的原因。
Corrosion resistance of cold rolled weathering steel of BNQ series was investigated by atmospheric exposure test,accelerated weathering test in room,electrochemical measurement and rust layer analysis.The results showed that the weathering steel is provided with both low corrosion rate and fine steadiness & adaptability for corrsion resistance.Moreover,the reason why BNQ series cold rolled weathering steel has high corrsion resistance is detailed.
