Description

1one

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

Электролит дл  анодного изолировани  карбидных и интерметаллидных фаз, содержащий хлористый литий и тиомочевину, о тличающийс  тем, что, с целью предотвращени  химического растворени  малоустойчивых структурных составл ющих при фазовом анализе сталей и сплавов, он дополнительно содержит трилон Б при следующем соотношении компонентов, г/л:The electrolyte for anodic isolation of carbide and intermetallic phases, containing lithium chloride and thiourea, is characterized in that, in order to prevent chemical dissolution of unstable structural components during phase analysis of steels and alloys, it also contains trilon B in the following ratio of components, g / l :
