| 配方组成： |
Temperature/70-75'F
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/95-110'F
Treatment time/30-60 minutes
Voltage/40 D.C. |
