摘要
开发含稀土的铝合金,既可开拓稀土的新用途,又能改善材料性能。我们研究了添加少量铈族混合稀土元素对铝镁硅合金建筑型材耐腐蚀性能的影响。结果表明,添加适量稀土,可以明显改善6063建筑材料的耐腐蚀性能。
The pit corrosion, uniform corrosion, sea water corrosion, and marine atmosphere corrosion of rare earth elements added 6063 wrought aluminum alloy are studied by voltammetric and gravimetric methods. The experim ental results show that the addition of a suitable small amount of RE elements can appreciably improve the corrosion resistance of the alloy. The distribution and function of RE elements in the alloy is preliminarily discussed by metallography and electron probe analysis.
