| 配方說明： |
Anodizing of Aluminum |
| 配方組成： |
Temperature/70-75F
Treatment time/15-30 minutes
Solution/16% Sulfuric Acid
The Aluminum part is made the anode (positive terminal) while a D.C.
voltage of from 12 to 15 is applied. the solution must be cooled to
maintain the temperature within the required limits. This treatment will
provide a hard, corrosion resistant coating on the aluminum surfaced.
Formula No.
Solution/6% Chromic Acid
Temperature/95-110F
Treatment time/30-60 minutes
Voltage/40 D.C. |
| 配制方法： |
This treatment is recommended where there is possibility of electrolyte entrapment which might result in corrosion of the aluminum part at some later date. |
