METHOD OF PRODUCING PROTECTIVE OXIDE FILM ON METALLIC SURFACE
FIELD: chemistry.SUBSTANCE: method of producing a protective oxide film on a metal surface includes the preparation of a matrix made of an iron powder by mixing the iron powder with water in a ratio of 85:15 by weight to give a heterophasic wetted mechanical mixture, compaction of the mixture at a p...

| description | FIELD: chemistry.SUBSTANCE: method of producing a protective oxide film on a metal surface includes the preparation of a matrix made of an iron powder by mixing the iron powder with water in a ratio of 85:15 by weight to give a heterophasic wetted mechanical mixture, compaction of the mixture at a pressing pressure of 1.4...1.6 GPa due to localized shear strains with achievement of residual porosity 1...3% and passivation of the matrix with providing a protective oxide film.EFFECT: increased corrosion resistance of the matrix material of the product base.1 ex
Изобретение относится к области материаловедения, а именно к снижению скорости коррозии металлической поверхности изделия. Способ получения защитной оксидной пленки на металлической поверхности включает получение матрицы-основы, выполненной из железного порошка, путем смешивания железного порошка с водой в соотношении 85:15 по массовой доле с получением гетерофазной увлажненной механической смеси, осуществление уплотнения упомянутой смеси при давлении прессования 1,4...1,6 ГПа за счет локализованных сдвиговых деформаций с достижением остаточной пористости 1...3% и пассивацию матрицы-основы с обеспечением защитной оксидной пленки. Обеспечивается повышенная коррозионная стойкость материала матрицы-основы изделия. 1 пр. |
