Description

Способ получени  защитного сло  на железных, стальных или чугунных издели хThe method of obtaining a protective layer on iron, steel or cast iron products

За влено 2 апрел  1940 года в НКВ за jV; 839 (313275) Опублик(1вано 31 августа 1944 голаFiled April 2, 1940 in the NKV for jV; 839 (313275) Publication (1st January 31 August 1944 goals

Предлагаемое изобретение касаетс  способа получени  защитного сло  на железных, стальных или чугунных издели х путём химической обработки их растворами нитратов при температуре не выше 115°.The present invention relates to a method for producing a protective layer on iron, steel or cast iron products x by chemical treatment with nitrate solutions at a temperature not higher than 115 °.

Способ состоит в том, что в нитратную ванну ввод т хромовую соль органической или неорганической кислоты совместно с хроматом щелочного металла. При этом поверхность изделий облагораживаетс , принимает красивую окраску в глубоко чёрный цвет и приобретает большую устойчивость к коррозии.The method consists in introducing the chromic salt of an organic or inorganic acid together with an alkali metal chromate into the nitrate bath. At the same time, the surface of the products is ennobled, takes a beautiful color in a deep black color and acquires greater resistance to corrosion.

Примерный состав нитратной ванны на 1 л воды: 500 г селитры, 100 г хромата натри  или кали , 100 г сернокислого хрома или квасцов .The approximate composition of the nitrate bath per 1 liter of water: 500 g of saltpeter, 100 g of sodium or potassium chromate, 100 g of chromium sulphate or alum.

Издели  обрабатывают при температуре не выше 115° в течение 5-20 минут.The products are treated at a temperature not higher than 115 ° for 5-20 minutes.

В составах, примен емых дл  получени  защитного сло , соль хрома можно заменить солью алюмини , при этом свойства раствора остаютс  без изменени .In the compositions used to form the protective layer, the chromium salt can be replaced by an aluminum salt, while the properties of the solution remain unchanged.

Прочность защитного сло , нанесённого предлагаемым способом на поверхность изделий из указанных металлов, может быть значительно повышена путём дополнительной обработки изделий в ванне щелочного оксидировани  известным способом при температуре выше 118° до или после основной обработки .The strength of the protective layer applied by the proposed method on the surface of products made from these metals can be significantly increased by further processing the products in an alkaline oxidation bath in a known manner at a temperature above 118 ° before or after the main treatment.
