| 中文摘要: |
| 采用硅酸盐方法对铝合金(3A21)进行表面处理,以盐雾测试作为评价其防腐效果的方法,优化了转化液中各个组分的浓度配比和工艺参数;同时讨论了添加剂对其防腐效果的影响。实验结果表明,硅酸钠的浓度对转化反应有很大的影响,添加剂对提高其防腐能力有一定的效果。 |
| 英文摘要: |
| A silicate method of aluminum alloy(3A21)surface treatment was studied.We used salt spray as an evaluation of its anticorrosion effect,and optimized the ratio of the various components of the conversion liquid and process parameters of the conversion. We also discussed the effect of the additives on anticorrosion. The study shows that the concentration of silicate has great affect on conversion consequence and the additive has a certain effect on enhancing the effect of aluminum's anticorrosion. |
