Beschreibung
Zusammenfassung:	A method for the protective oxide covering application on an aluminium and its alloys involves washing and treatment of metal surface, application of anode-oxide covering and final treatment. In accordance with the invention, applicated anode-oxide covering is additionally subject to the to heat treatment at the temperature of 80-95 DEGREE C in water solution of ethyl alcohol in the presence of iodine during 15-25 min., after which the compression in colloid suspension of resin at the temperature of 180-200 DEGREE C during 50-70 min. is carried out, and as final treatment, drying is carried out to the complete desiccation. Solution for heat treatment and colloid suspension are also claimed for the compression of protective oxide covering. The invention provides increasing of protective, wearproof and anticorrosion properties of oxide coverings.
