Description
Изобретение относитс к области изыскани электролитов дл электрохимического травлени стали, в частности дл вы влени макроструктуры аустенитных нержавеющих сталей. Известен электролит дл электрохимического травлени металлов, содержащий: Сол на кислота ( / 1,16), смз Лимонна кислота, г Этиловый снирт, см До 1000 Вода, см Предлагаемый электролит отличаетс от известного тем, что в него дополнительно введены хлорна медь и хлористый магний. Это обеспечивает четкое вы вление дендритной структуры стали. Предлагаемый электролит имеет следующий состав, вес. % Сол на кислота Лимонна кислота Этиловый спирт Хлорна медь 0,5-1,5 Хлористый магний Вода остальное 100 20 При составлении электролита необходимо сначала растворить все соли и кислоты в рекомендуемом количестве воды, а затем добавить спирт. Электрохимическое травление в таком электролите провод т в течение 10-40 сек при комнатной температуре и плотности тока 0,2-0,5 а/см. В качестве катода используетс пластина из нержавеющей стали. Предмет изо-бретени Электролит дл электрохимического травлени стали, содержащий сол ную и лимонную кислоты, этиловый спирт и воду, отличающийс тем, что, с целью четкого вы влеии дендритной структуры стали, в него дополнительно введены хлорна медь и хлористый магний при следующем соотнощении компо%: нентов, вес. Сол на кислота Лимонна кислота 50-60 Этиловый спирт Хлорна медь 0,5-1,5 1-3,5 Хлористый магний .Вода остальноеThe invention relates to the field of finding electrolytes for the electrochemical etching of steel, in particular for identifying the macrostructure of austenitic stainless steels. Electrolyte is known for electrochemical etching of metals, containing: Hydrochloric acid (/ 1.16), cm3 Citric acid, g Ethyl residue, cm Up to 1000 Water, cm The proposed electrolyte differs from the known one in that it additionally contains chlorine copper and magnesium chloride . This provides a clear indication of the dendritic structure of the steel. The proposed electrolyte has the following composition, weight. % Hydrochloric acid Citric acid Ethyl alcohol Chlorne copper 0.5-1.5 Magnesium chloride Water the rest 100 20 When preparing the electrolyte, you must first dissolve all salts and acids in the recommended amount of water, and then add alcohol. Electrochemical etching in such an electrolyte is carried out for 10-40 seconds at room temperature and a current density of 0.2-0.5 a / cm. A stainless steel plate is used as the cathode. Subject of invention Electrolyte for electrochemical etching of steel containing hydrochloric and citric acids, ethyl alcohol and water, characterized in that, in order to clearly determine the dendritic structure of the steel, chlorine copper and magnesium chloride are added to it at the following ratio of% : nantov, weight. Solic acid Citric acid 50-60 Ethyl alcohol Chlorne copper 0.5-1.5 1-3.5 Magnesium chloride. Water the rest
