中文摘要:
      目的 研究在温度和表面粗糙度不同的情况下, 6061铝合金的耐蚀性能变化, 并研究表面硫酸、 硼酸硫酸阳极氧化对提高6061铝合金耐蚀性能的作用。方法 对试样进行中性盐雾试验和电化学实验。结果 随着表面粗糙度的下降, 6061铝合金的耐蚀性有所提高, 且表面经过阳极氧化后, 试样表面盐粒沉积量大幅下降, 腐蚀面积有所减少。随着温度升高, 6061铝合金的耐蚀性下降, 而当温度达到55 ℃时, 试样表面出现了一定的钝化现象, 当温度继续升高, 钝化现象消失, 腐蚀速率重新上升。结论 随温度和表面粗糙度的提高, 6061 铝合金的耐蚀性能下降, 而 55 ℃为6061铝合金较好的钝化温度。
英文摘要:
      Objective To investigate the corrosion behaviour of 6061 aluminum alloy in conditions of different temperatures and surface roughness and the enhancement of corrosion resistance of the alloy by using surface sulphuric acid anodizing and boracic-sulphuric acid anodizing. Methods The salt spray tests and the electrochemical experiments were conducted on samples. Results The corrosion resistance of the alloy increased along with the decrease of the surface roughness, the deposited salt particles on the alloy surface reduced remarkably and the corrosion area decreased as the surface anodized. In addition, the alloy corrosion resistance decreased as the temperature raised, but the samples were passivated when the temperature reached 55 ℃, and the passivation resolved and the corrosion rate raised again as the temperature raised continuously. Conclusion The results show that the corrosion resistance of 6061 aluminum alloy decreases as the surface roughness and the temperature rise, and 55 ℃ is a proper passivation temperature for 6061 aluminum alloy.
