How To Distinguish The Type Of Anodizing

In terms of anodization, whether it is the content of the knowledge or difficult problems, it is within our scope of study because it is within its knowledge system.

Therefore, if you want to fully understand the anodization, then none of these things can be omitted. Then, in order to save time and improve learning efficiency, we will start immediately, I hope everyone will not miss it.

1. Is the natural anodization of the workpiece the same as the anodization of the workpiece?

For the two, literally, there are two more words in the former, and there seems to be no big difference. However, from a professional perspective, the two are still very different.

Natural color anodization, which is achieved by electrolysis. In color, it is known to remain with the color before oxidation. Anodizing is the coloring of the oxide film after electrolysis to achieve the purpose. Therefore, there are obvious changes in color. In addition, the number of steps is more than that of anodizing services.

2. What is the thickness of the anodic oxide film formed at normal temperature?

The anodic oxidation performed at normal temperature, the thickness of the formed oxide film is generally 5 to 15 microns, and the hardness is 200-400HV. The corresponding low-temperature oxidation, which is called hard oxidation, is different from anodic oxidation. Because in the film thickness, it can reach 250 microns.

3. Are anodized aluminum alloy and electroplated aluminum alloy the same?

Although anodized aluminum alloy and electroplated aluminum alloy are both surface-treated on aluminum alloy materials and are similar in form, they are fundamentally different. Because of the anodization, it is not easy to fall off, and the environmental protection during machining belongs to the third level. The electroplating is prone to fall off, and the environmental protection during machining is first-class. Therefore, there are still many differences.
