1. After degreasing anodized in the following solution:
concentrated sulfuric acid 22 g/l in 1-1.5
A/dm2 The dc is strong Under the degree of impregnation 10-15 min
,Again in saturated potassium
dichromate solution,in 95 - 100 c. The impregnation 5-20 min, And
2. After degreasing chemical treatment in the following solution:
Potassium dichromate 66
Sulfuric acid (96%) 666water 1000 in 70 c. The impregnation 10 min
And then washed, dry.
