differences between anodizing and chemical oxidation of aluminium discs

Today we are going to talked about the differences between anodizing and chemical oxidation of aluminium discs. And today we are going to introduce it from the material and structure perspectives. Now let’s get started!

1. Whether electricity is required.

Anodic oxidation is carried out under the condition of high voltage electricity, it is a kind of electrochemical reaction process; chemical oxidation does not need to be electrified, but only needs to be immersed in the potion on the line, it is a pure chemical reaction.

2. Length of time.

The anodic oxidation of aluminium discs takes a long time, often several minutes; chemical oxidation takes only a few dozen seconds.

3. Wear resistance: good or bad.

Aluminum round anodic oxidation generated film has a few microns to dozens of microns, and hard wear resistance; chemical oxidation generated film is only 0.01-0.15 microns or so, wear resistance is not very good, but both conductive and resistant to atmospheric corrosion, which is its advantage.

4. Conductivity.

Aluminum round anodic oxide film is originally non-conductive; chemical oxidation generated film is really thin, so it is conductive.

So this is the rough introduction of the differences between anodizing and chemical oxidation of aluminium discs.
