Изобретение относитс  к области химической обработки металлов, в частности к глубокому травлению алюминиевых сплавов.This invention relates to the field of chemical processing of metals, in particular, to deep etching of aluminum alloys.

Известен раствор дл  глубокого травлени  алюминиевых сплавов, содержащий едкий натр и тиомочевину.Known solution for deep etching of aluminum alloys containing caustic soda and thiourea.

Предложенный раствор отличаетс  от известного введением в его состав триэтаноламина при определенном соотношении компонентов , что повышает чистоту обрабатываемой поверхности.The proposed solution differs from that known by introducing triethanolamine into its composition at a certain ratio of components, which increases the purity of the treated surface.

Раствор содержит едкий натр, тиомочевипу и триэтаноламин при следующем соотношении компонентов, г/л:The solution contains caustic soda, thiourea and triethanolamine in the following ratio of components, g / l:

Едкий натр150-170Caustic soda 150-170

Тиомочевина6- 10Thiourea6-10

Триэтаноламин20- 30.Triethanolamine 20-30.

При травлении в данном растворе достигаетс  чистота поверхности п того-шестого класса . Скорость травлени  1,5-3 мм/час.By etching in this solution, the purity of the surface of the fifth-sixth class is achieved. The etching rate of 1.5-3 mm / hour.

При одновременном присутствии в щелочном растворе триэтаноламина и тиомочевины повышение чистоты поверхности достигаетс  а счет одновременного торможени  активных центров поверхности и перевода в растворимое состо ние труднорастворимых в щелочи легирующих компонентов сплавов при травлении различных полуфабрикатов.With the simultaneous presence of triethanolamine and thiourea in an alkaline solution, an increase in surface purity is achieved by simultaneously slowing down the active centers of the surface and rendering the alloying components of the alloys that are hardly soluble in alkali when etching various semi-finished products.
