针对铝合金的阳极氧化,比较多,可以应用在日常生活中,以为这种工艺的特性,使铝件表面产生坚硬的保护层,可用于生产厨具等日用品。
The anodic oxidation of aluminum alloys is quite common, which can be applied to daily life. It is considered that the characteristics of this technology make the surface of aluminum pieces produce a hard protective layer, and it can be used to produce Kitchenware and other daily necessities.
近十年来,我国的铝氧化着色工艺技术发展较快,很多工厂已采用了新的工艺技术,并且在实际生产中积累了丰富的经验。已经成熟和正在发展的铝及其合金阳极氧化工艺方法很多,可以根据实际生产需要,从中选取合适的工艺。
Over the past ten years, the technology of aluminum oxidation and coloring has been developing rapidly. Many factories have adopted new technology, and have accumulated rich experience in actual production. There are many methods for the anodizing of aluminum and its alloys, which are already mature and developing, and the suitable process can be selected according to the actual production needs.
在选取氧化工艺之前,应对铝或铝合金材质情况有所了解。因为,材料质量的优劣、所含成份的不同,是会直接影响到铝制品阳极氧化后的质量的。
Before the oxidation process is selected, the material of aluminum or aluminum alloy should be understood. Because of the quality of the material and the different components, it will directly affect the quality of the anodized aluminum products.
比如,铝材表面如有气泡、划痕、起皮、粗糙等缺陷,经阳极氧化后,所有疵病依然会显露出来。而合金成份,对阳极氧化后的表面外观,也产生直接的影响。
For example, aluminum surface such as air bubbles, scratches, peeling, rough defects, after anodic oxidation, all defects will still be revealed. The composition of the alloy also has a direct effect on the surface appearance of the anodic oxidation.
比如,含1~2%锰的铝合金,氧化后呈棕蓝色,随铝材中含锰量的增加,氧化后的表面色泽从棕蓝色到深棕色转化。
For example, the aluminum alloy containing 1 to 2% Mn is brown after oxidation. With the increase of manganese content in the aluminum material, the surface color after oxidation is transformed from brown to dark brown.
含硅0.6~1.5%的铝合金,氧化后呈灰色,含硅3~6%时,呈白灰色。
The aluminum alloy containing 0.6 ~ 1.5% silicon is gray after oxidation and white gray when the silicon is 3 ~ 6%.
含锌的呈乳浊色,含铬的呈金黄至灰色的不均匀色调,含镍的呈淡黄色。
The zinc content is opacification, and the chromic is golden to gray inhomogeneous hue, and the nickel is pale yellow.
一般而言,只有含镁和含钛量大于5%的铝含金,经氧化后可以得到无色透明且光亮、光洁的外观。
In general, only magnesium and titanium containing more than 5% of the titanium containing gold can be oxidized and transparent and bright and smooth after oxidation.
在选择好铝及铝合金材料后,自然就要考虑到选取合适的阳极氧化工艺。目前,我国广泛应用的硫酸氧化法、草酸氧化法及铬酸氧化法。
After the selection of aluminum and aluminum alloy materials, it is natural to take into consideration the selection of the appropriate anodizing process. At present, the sulfuric acid oxidation, oxalic acid oxidation and chromic acid oxidation are widely used in China.
