Anodizing plants

Anodizing process

The anodizing process (abbreviation for electrolytic oxidation of aluminium) is a surface technology method for creating an oxidic protective layer on aluminium through anodic oxidation. In contrast to galvanic coating processes, the protective layer is not deposited on the workpiece, but an oxide or hydroxide is formed by converting the uppermost metal zone. The result is a 5 to 25 micrometer thin layer that protects against corrosion. The natural oxide layer of aluminum is only a few nm.

Anodizing

First, the aluminium parts are pre-treated, i.e. cleaned and pickled to remove adhering dirt and the thin natural oxide layer. This is followed by the actual anodizing, sometimes the fresh porous layer is then dyed with dyes, and finally sealing is carried out, usually simply with hot water (hot rinsing). There is also the option of chemical sealing (treatment basin: pre-sealing, sealing). The anodizing process uses electrolysis. The cathode (negative electrode) breaks down the oxonium (H3O+) contained in the acid into hydrogen and water. The hydrogen is released.

Electrolytic dyeing

Electrolytic dyeing is carried out with alternating voltage. The electrolyte contains a coloring metal salt. The duration of the electrolysis depends on the desired color depth. The metal ions penetrate deep into the pores of the coating. The pores, which are thus partially filled with metal, now cause a lightfast coloration through absorption and scattering effects.

Compacting

To prevent the accumulation of corrosive substances,
the pores must be sealed. The anodized and
Any colored aluminum is compacted in a solution.
This results in a reaction between the aluminum oxide
and water. The water absorption leads to an increase in volume,
so that the pores are constricted and then closed.
