Claims (3)

1. Способ формирования защитных покрытий, преимущественно арматуры для газовых и жидких потоков, включающий формирование слоя алюминия или анодируемого алюминиевосодержащего сплава на обезжиренные рабочие поверхности, подлежащие покрытию, отличающийся тем, что после формирования слоя алюминия или алюминиевосодержащего материала его поверхность (или поверхность алюминиевосодержащего материала) механически обрабатывают до восстановления геометрии поверхности, затем поверхность слоя очищают и обезжиривают и подвергают микродуговому оксидированию в слабощелочном электролите, содержащем 3 г/л КОН, 10 г/л жидкого стекла при плотности тока 10-15 А/дм2, при температуре электролита 40-60°С до получения слоя оксида алюминия толщиной 100-250 мкн.1. The method of forming protective coatings, mainly valves for gas and liquid flows, including the formation of a layer of aluminum or anodized aluminum-containing alloy on fat-free working surfaces to be coated, characterized in that after the formation of a layer of aluminum or aluminum-containing material, its surface (or the surface of aluminum-containing material) machined until the surface geometry is restored, then the surface of the layer is cleaned and degreased and subjected to microarc oxidation in a slightly alkaline electrolyte containing 3 g / l KOH, 10 g / l of liquid glass at a current density of 10-15 A / dm 2 , at an electrolyte temperature of 40-60 ° C to obtain a layer of aluminum oxide with a thickness of 100-250 microns. 2. Способ по п.1, отличающийся тем, что формирование слоя алюминия осуществляют нанесением покрытия на корпус детали или поверхность изделия.2. The method according to claim 1, characterized in that the formation of the aluminum layer is carried out by coating the body of the part or the surface of the product. 3. Способ по п.1, отличающийся тем, что формирование слоя алюминия осуществляют изготовлением корпуса детали, узла и изделия, подлежащего обработке защитным покрытием, из анодируемого алюминиевого сплава.3. The method according to claim 1, characterized in that the formation of the aluminum layer is carried out by the manufacture of the body of the part, assembly and product to be treated with a protective coating from anodized aluminum alloy.
