Abstract

FIELD: coating application. SUBSTANCE: surface is treated in sulfuric, formic, oxalic, citric or sulfosalycilic acid solution by alternating low-frequency current with equal duration of anode and cathode pulses and different ratio of current amplitudes for anode and cathode half- periods. As a result, porous oxide layer is formed. EFFECT: increased adhesion of coating to substrate due to anchor engagement on porous surface.

Claims (1)

Способ обработки поверхности изделий из алюминия или его сплавов перед нанесением на ней покрытия функционального назначения, заключающийся в анодном окислении алюминия постоянным током, отличающийся тем, что анодное окисление алюминия и его сплавов осуществляется с использованием переменного асимметричного тока в кислом растворе электролита.The method of surface treatment of products from aluminum or its alloys before applying a functional coating to it, which consists in anodic oxidation of aluminum by direct current, characterized in that the anodic oxidation of aluminum and its alloys is carried out using an alternating asymmetric current in an acidic electrolyte solution.
