Description
Изобретение относитс к металлургии и может быть использовано дл проведени металлографического анализа качества металлов .This invention relates to metallurgy and can be used to perform metallographic analysis of the quality of metals.
Целью изобретени вл етс снижение стоимости реактива при повышении его экологичности .The aim of the invention is to reduce the cost of the reagent while increasing its environmental friendliness.
Пример. Готовили реактив состава, мас.%:Example. Preparing the reagent composition, wt.%:
Хлористый натрий0,01 - 0,02Sodium Chloride 0.01 - 0.02
Анодна активированна вода при рН 2,0 - 3,0ОстальноеAnodic activated water at pH 2.0 - 3.0 Else
Реактивы готовили следующим образом .The reagents were prepared as follows.
В активатор наливали водопроводную оду. Врем электролиза 10 мин. По истечении этого времени анодна активированна рода имела рН 2,0 - 3,0. Затем в нее добавл ли хлористый натрий.In the activator poured tap ode. Electrolysis time 10 min. At the end of this time, the anodically activated kind had a pH of 2.0-3.0. Then sodium chloride was added to it.
Перед травлением шлиф тщательно обезжиривали тампоном, смоченным в спирте и тщательно протирали насухо. Обезжиренный шлиф полностью погружали в реактив, подогретый до 30 - 35°С полированной поверхностью вверх. Реактив покрывал поверхность шлифа слоем не менее 2 мм. Поверхность шлифа периодически протирали ватным тампоном, не вынима шлифа из реактива дл удалени окисной пленки. После травлени шлиф промывали в спирте и высушивали насухо.Before etching, the section was thoroughly degreased with a swab dipped in alcohol and thoroughly wiped dry. Fat-free grinding is completely immersed in the reagent, heated up to 30 - 35 ° C with the polished surface up. The reagent covered the surface of the thin section with a layer of at least 2 mm. The surface of the thin section was periodically wiped with a cotton swab, without removing the thin section of the reagent to remove the oxide film. After pickling, the polish was washed in alcohol and dried dry.
Травлению подвергали шлифы из серого чугуна.Gray cast iron sections were etched.
. Использование предлагаемого реактива позвол ет вы вл ть внутрикристаллическую ликвацию кремни в высокоуглеродистых сплавах без применени пикриновой кислоты; экономить материальные ресурсы; исключить вли ние вредных паров дл человеческого организма и окружающей среды.. The use of the proposed reagent makes it possible to detect the intracrystalline segregation of silicon in high-carbon alloys without the use of picric acid; save material resources; eliminate the effect of harmful vapors for the human body and the environment.
В таблице приведены экономические характеристики растворов.The table shows the economic characteristics of the solutions.
