Abstract (en)
[origin: US4455201A] Aluminized parts are anodized in an aqueous bath which contains 1050 to 1040 g per L of sulfuric acid with a density of 1.84 and optionally 1 to 100 g of a polyhydroxy alcohol and 1 to 100 g of a multibasic organic acid. The anodizing is carried out at a pH value of less than 1 with a current density of 0.5 to 3 A/dm2 at 0 DEG to 30 DEG C. The method can be used with partially aluminized parts without destroying the base material.
