針對鋁合金的陽極氧化,比較多,可以應(yīng)用在日常生活中,以為這種工藝的特性,使鋁件表面產(chǎn)生堅硬的保護(hù)層,可用于生產(chǎn)廚具等日用品。
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.
近十年來,我國的鋁氧化著色工藝技術(shù)發(fā)展較快,很多工廠已采用了新的工藝技術(shù),并且在實際生產(chǎn)中積累了豐富的經(jīng)驗。已經(jīng)成熟和正在發(fā)展的鋁及其合金陽極氧化工藝方法很多,可以根據(jù)實際生產(chǎn)需要,從中選取合適的工藝。
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.
在選取氧化工藝之前,應(yīng)對鋁或鋁合金材質(zhì)情況有所了解。因為,材料質(zhì)量的優(yōu)劣、所含成份的不同,是會直接影響到鋁制品陽極氧化后的質(zhì)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,鋁材表面如有氣泡、劃痕、起皮、粗糙等缺陷,經(jīng)陽極氧化后,所有疵病依然會顯露出來。而合金成份,對陽極氧化后的表面外觀,也產(chǎn)生直接的影響。
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%錳的鋁合金,氧化后呈棕藍(lán)色,隨鋁材中含錳量的增加,氧化后的表面色澤從棕藍(lán)色到深棕色轉(zhuǎn)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%的鋁合金,氧化后呈灰色,含硅3~6%時,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%.
含鋅的呈乳濁色,含鉻的呈金黃至灰色的不均勻色調(diào),含鎳的呈淡黃色。
The zinc content is opacification, and the chromic is golden to gray inhomogeneous hue, and the nickel is pale yellow.
一般而言,只有含鎂和含鈦量大于5%的鋁含金,經(jīng)氧化后可以得到無色透明且光亮、光潔的外觀。
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.
在選擇好鋁及鋁合金材料后,自然就要考慮到選取合適的陽極氧化工藝。目前,我國廣泛應(yīng)用的硫酸氧化法、草酸氧化法及鉻酸氧化法。
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.
