ELECTROLYTE FOR SIMULTANEOUS DEGREASING AND ETCHING ALUMINIUM AND ALLOYS THEREOF BEFORE ANODIC TREATMENT

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to detergent and etching solutions used for preparing aluminium alloys before anodic treatment. The electrolyte contains the following, in g/l: sodium hydroxide 35-45; sulphosalicylic acid 15-25; oxyphos B 1-2; pyrodoxine hydrobromide 0.2-0.4. ^ EFFECT: combination of degreasing and etching processes enables to cut on processing area and labour input in preparing components without deterioration of decorative appearance and improvement of protective anti-corrosion properties of oxide films on the surface of the components. ^ 4 tbl
