- Typical parameters of the process
Process | Temperature [°C] | Chemicals | Details | Literature |
General anodizing | 15-25 | 150-230 g/l H2SO4 | anodizing voltage: 17-22 V; film thickness: 5- 30 μm | BAT for the surface treatment of metals & plastics, 2006 |
Hard anodizing | <5 | film thickness: 25- 250 μm | ||
Chromic acid anodizing | 38-42 | 30-100 g of chromic acid/l | film thickness: 2-5 μm |
