| Al-Si合金由于其良好的性能已在工业中得到了广泛的应用。阳极氧化成为铝合金铸件表面处理的一种重要方式，而阳极氧化膜色差直接影响到铸件的表面质量、使用寿命及外观要求。探讨了影响铸铝阳极氧化的因素，研究了铸铝合金的表面预处理和阳极氧化工艺，讨论了铸铝合金的表面预处理和工艺条件对阳极氧化膜性能的影响，据此优化工艺，获得了合适的表面预处理方法和阳极氧化最佳工艺条件。该工艺操作简便，节约能源，生产效率高，易于推广应用。 |
| 英文摘要: |
| Al-Si alloy has been widely applied in industry for its good properties. Anodization is the important process of surface pretreatment for Al-alloy casting and the anodising membrane chromatism of aluminium alloy casting directly influenced the surface quality, service life and appearance. Influence factors of quality of cast aluminium positive pole oxidizing were discussed. Processes of surface pretreatment and anodization of cast Al alloys were investigated, effects of surface pretreatment and echnological conditions of cast Al alloys on corrosion resistance and thickness of anodized film were discussed. Based on this optimum technology, applicable method of surface pretreatment and technological conditions of anodization were obtained. The technology was simple and efficient. |
