Изобретение относитс к фазовому химическому анализу.The invention relates to phase chemical analysis.
Известен электролит дл изолировани карбидов и интерметаллидов при анодном растворении сталей и сплавов, содержащий хлористый литий и тиомочевину. Предлагаемый электролит дополнительно содержит трилон-Б . Это обеспечивает выделение малоустойчивых структурных составл ющих без разрушени в электролите.A known electrolyte for insulating carbides and intermetallic compounds during anodic dissolution of steels and alloys containing lithium chloride and thiourea. The proposed electrolyte further comprises Trilon-B. This ensures the release of unstable structural components without destruction in the electrolyte.
Предлагаемый электролит содержит, г/л: Трилон-Б20- 30The proposed electrolyte contains, g / l: Trilon-B20-30
Хлористый литий200-500Lithium chloride 200-500
Тиомочевина10- 20Thiourea 10-20
Электролит позвол ет выдел ть карбиды железа, богатые железом карбиды сложного состава, химически малоустойчивые интерметаллиды .The electrolyte allows the release of iron carbides, iron-rich carbides of complex composition, chemically unstable intermetallic compounds.
Процесс ведут при комнатной температуре и плотности тока 0,02-0,05 а/см.The process is carried out at room temperature and a current density of 0.02-0.05 a / cm.
Предмет изобретени Subject invention
