Table 2 Pretreatment code and pretreatment type of anodized film
Preprocessing code preprocessing type description
E0 degreasing and deoxidation
Prior to anodizing, only the surface is degreased and deoxidized, scorched and scratched.
The traces are still visible. Corroded surface that is difficult to see before treatment, visible after treatment
E1 polishing
Grinding results in a relatively uniform but matt surface. This process can remove most of the table
Surface defects, the treatment effect is determined by the roughness of the abrasive, and the surface has scratch marks.
E2 brushing
Mechanical brushing results in a uniform, shiny surface with brush marks. Can only remove part of the table
Surface defect
E3 polishing mechanical polishing can get a glossy surface, but only remove some surface defects
E4 polishing and brushing
Polishing and brushing results in a uniform, shiny surface with mechanical surface defects removed.
This treatment removes corrosion, but E0 or E6 treatment can cause corrosion to be visible
E5 polishing and polishing
Polished and polished to give a smooth, shiny surface, mechanical surface defects can go
except. This treatment removes corrosion, but E0 or E6 treatment may cause corrosion to visualize
visible
E6 chemical etching
After degreasing, it can be treated in a special alkaline etching solution to obtain smooth or matt
s surface. Mechanical surface defects have been mitigated but cannot be completely removed. This has been processed
Afterwards, the corrosion of the metal surface may be visually visible. Mechanical pretreatment before etching can
Remove corrosion, but proper handling and storage of materials to prevent corrosion is a better choice
E7 chemical or electrochemical polishing
After degreasing, the surface is placed in a steam degreasing machine or a non-etching cleaning machine.
Process or electrochemical brightening process to obtain a very bright surface. This process only
Can remove a small amount of surface defects, corrosion can be visually visible

Polishing
After grinding and polishing, chemical or electrochemical brightening is performed. This process can get light
Sliding, shiny surfaces, surface mechanical defects and initial corrosion can generally be removed
