Processing of different types of metal

Oxidation also helps to hide minor surface defects such as scratches or abrasions.

Unlike regular steel, stainless steel is difficult to process as a relatively inert metal. To solve this problem, stainless steel is coated with nickel, and only then is oxidation carried out. Scientists are actively developing special pastes that will reduce the inert properties of the outer layer of stainless steel.

Anodizing of steel is carried out taking into account the properties and characteristics of the metal. For other compounds, these conditions may be unacceptable. Let's consider the features of processing individual metals and alloys based on them.

Anodizing of copper and its alloys
This metal is very difficult to oxidize. The electrochemical chinese overseas america data is considered optimal, as a result of which the color changes. Phosphate or oxalate solutions are used as a working mixture.

The process has high technological requirements, so it is extremely rare in practice.

Titanium anodizing
The procedure is considered mandatory, since the oxide film not only increases the strength of the workpiece, protecting it from mechanical damage, but also changes color in a wide range depending on the voltage level during the working cycle.

Almost any acid is suitable for processing titanium.

Silver anodizing
For anodic oxidation of silver, experts recommend using liver of sulfur - it can impart blue or purple shades without changing the properties of the silver surface.
