研究了305铝合金、166铝合金、铍和不锈钢在室温(6—31℃)的高纯水、低纯水以及含硼、钆等的水介质中的腐蚀行为。试验结果表明:经阳极氧化后的305铝合金具有良好的抗低温腐蚀的能力。166铝合金耐低温腐蚀能力不如305铝合金。铍在含硼的水介质中发生严重的点蚀和溃疡腐蚀,但铍在含钆的水介质中则显示出良好的耐蚀性。 The corrosion behavior of 305 aluminum alloy, 166 aluminum alloy, beryllium and stainless steel in high purity water, low purity water and boron, gadolinium and other aqueous media at room temperature (6-31 ℃) was studied. The experimental results show that: the anodized 305 aluminum alloy has good resistance to low temperature corrosion. 166 aluminum alloy low temperature corrosion resistance than 305 aluminum. Beryllium undergoes severe pitting and ulcer corrosion in boron-containing aqueous media, but beryllium shows good corrosion resistance in gadolinium-containing aqueous media.
