Description

РАСТВОР ДЛЯ ОСВЕТЛЕНИЯ МЕТАЛЛОВ И СПЛАВОВSOLUTION FOR LIGHTING METALS AND ALLOYS

1one

Изобретение относитс  к области травлени  металлов и сплавов, в частности к осветлению после гидридного травлени .The invention relates to the field of etching of metals and alloys, in particular to the clarification after hydride etching.

Известен раствор дл  осветлени  металлов и сплавов, содержапдий серную кислоту, азотнокислый натрий и ингибитор.A known solution for clarifying metals and alloys, containing sulfuric acid, sodium nitrate and an inhibitor.

Предлагаемый раствор отличаетс  от известного тем, что в его состав введено хлорное железо при определенном соотношении компонентов .The proposed solution differs from the known one in that it contains ferric chloride at a certain ratio of components.

Это позвол ет повысить качество обработки и интенсифицировать процесс.This makes it possible to improve the quality of processing and intensify the process.

Раствор имеет следующий состав, вес. %: серна  кислота15-21,7The solution has the following composition, weight. %: sulfuric acid15-21,7

В качестве ингибитора в раствор рекомендуетс  вводить мочевину, тиомочевину, гипосульфит натри , катапин, уротропин, серный цвет.Urea, thiourea, sodium hyposulphite, catapine, urotropin, sulfur color are recommended as an inhibitor in the solution.

Пример. Образцы хромел , марганцовистого никел  и констаптана после гидриднойExample. Samples of chromel, manganese nickel and constaptan after hydride

обработки осветл ют в растворе, содержащем 20 вес. % серной кислоты, 5,5 вес. % азотпокислого натри , 3,4 вес. % хлорного железа и 0,06 вес. % мочевины, при в течение 3 мин.Treatments are clarified in a solution containing 20 wt. % sulfuric acid, 5.5 wt. % sodium nitrate, 3.4 wt. % ferric chloride and 0.06 wt. % urea, if within 3 minutes

Потери г шталла составл ют дл  хромел  4,2 кг/т, дл  марганцовистого никел  - 3,7 кг/т, дл  константана - 6,0 кг/т.The loss of grams of stall is 4.2 kg / ton for chromel, 3.7 kg / ton for manganese nickel, and 6.0 kg / ton for constantan.

Поверхность обработанных образцов матова , чиста , ровна .The surface of the treated samples is dull, clean, smooth.
