氧化和镀漆都是做手板模型时常见的表面处理工艺，镀漆是在手板的表面喷上一层油漆，只需客户提供相应的潘通色号，手板厂家就能在手板表面喷上相应的色泽。而氧化则是将铝合金手板浸泡在药水中，让药水腐蚀到铝合金手板里面，使之发生氧化反应，从而改变铝合金手板的色泽。虽然氧化和镀漆都是使手板的表面有色泽，但是它们之间还是有区别的，主要体现在以下这两方面。

Oxidation and coating are common surface treatment processes when making prototype boards. Coating is the process of spraying a layer of paint on the surface of the prototype board. With the customer providing the corresponding Pantone color code, the prototype board manufacturer can spray the corresponding color on the surface of the prototype board. Oxidation, on the other hand, involves soaking the aluminum alloy hand board in a solution that corrodes it, causing it to undergo an oxidation reaction and changing the color of the aluminum alloy hand board. Although oxidation and coating both give the surface of the handboard a color, there are still differences between them, mainly reflected in the following two aspects.

针对的原料不一样，镀漆可以适用于做手板的很多原料——金属、塑胶以及树脂，而氧化是只有铝合金手板才有的工艺。

The target materials are different, and coating can be applied to many materials used for making handboards - metal, plastic, and resin, while oxidation is a process that only aluminum alloy handboards have.

色泽的持久性不一样，由于镀漆只是在手板表面喷上一层油漆，随着时间的流逝会有脱落的，而氧化是将铝合金手板浸泡在药水中，使表面形成一层氧化膜。由于氧化产生的氧化铝是一种稳定的物质，很难与空气中的氧化发生反应，所以表面的色泽比较稳定，不易脱落。氧化出来的色泽有金属质感，看上去高端大气上档次，使用镀漆的话，是无论如何也调不出那种作用来，镀漆的色泽能够达到与氧化出来的色泽有80%的相似度已经很不错了。

The durability of the color is different, as the plating only sprays a layer of paint on the surface of the handboard, which will peel off over time. On the other hand, oxidation involves soaking the aluminum alloy handboard in a solution to form an oxide film on the surface. Due to the fact that aluminum oxide produced by oxidation is a stable substance that is difficult to react with oxidation in the air, the surface color is relatively stable and not easy to peel off. The oxidized color has a metallic texture, giving it a high-end, atmospheric and upscale appearance. If you use paint coating, it is impossible to achieve that effect. The color of paint coating can reach 80% similarity to the oxidized color, which is already very good.

通常情况下，不锈钢和铜是不能氧化的，只有铝合金才能发生氧化，但是不一样的铝合金材料，它们的氧化作用也各不相同，像铝合金7075的氧化作用就不好，因为它的成分里面含有铜，通常以5和6开头的铝合金都可以氧化，而铝合金6061-T6的氧化作用佳。氧化之前，通常需要喷砂，否则会影响铝合金手板的美观度；同样，如果铝合金手板表面抛高光就去氧化，就是高光的氧化作用。如果你要做的铝合金手板是本色的话，只需打磨光滑，然后再进行喷砂。

Normally, stainless steel and copper cannot oxidize, only aluminum alloys can oxidize. However, the oxidation effect of different aluminum alloy materials is also different. For example, the oxidation effect of aluminum alloy 7075 is not good because it contains copper in its composition. Aluminum alloys starting with 5 and 6 can oxidize, while aluminum alloy 6061-T6 has better oxidation effect. Before oxidation, sandblasting is usually required, otherwise it will affect the aesthetic appearance of the aluminum alloy hand board; Similarly, if the surface of the aluminum alloy handboard is polished with highlights, it will undergo oxidation, which is the oxidation effect of the highlights. If the aluminum alloy handboard you want to make is in its natural color, just polish it smooth and then sandblasting it.

当铝合金手板经过氧化后，生成的氧化铝是一种比较稳定的物质，不会再次与空气中的氧发生反应了，因此能长久的保持这种色泽。铝合金手板氧化的目的主要有两个：一是防止手板表面被腐蚀，二是提高手板的美观度。

When aluminum alloy handboards are oxidized, the generated aluminum oxide is a relatively stable substance that will not react with oxygen in the air again, so it can maintain this color for a long time. The main purposes of aluminum alloy hand board oxidation are twofold: first, to prevent corrosion on the surface of the hand board, and second, to improve the aesthetics of the hand board.
