Способы электрополировани металлов в ваннах, содерлсзщих концентрированные растворы фосфорной и серной кислот, известны. В этих способах дл образовани полированного сло изделие завешиваетс на анод в ваину специального состава. При определенных плотност х тока и температуре ванны происходит сглаживание неровностей и образование полированного сло .Methods for electropolishing metals in baths containing concentrated solutions of phosphoric and sulfuric acids are known. In these methods, to form a polished layer, the product is hung on the anode into a vaine of a special composition. At certain current densities and bath temperatures, irregularities are smoothed and a polished layer is formed.
В предлагаемом, согласно изобретению , способе ванна дл электрохимического полировани содержит вместо концентрированной ортофосфорной кислоты ее соли - фосфат аммони или тринатрийфосфат.In the method proposed according to the invention, the electrochemical polishing bath contains, instead of the concentrated orthophosphoric acid, its salt — ammonium phosphate or trisodium phosphate.
Электроцолирование нержавеющей стали производитс в ванне следуюОтв . редактор М. М. АкишинElectrozolation of stainless steel is carried out in the bath following. editor M. M. Akishin
щего состава: 400 г аммонийфосфата или 500 г тринатрийфосфата, 500 г серной кислоты и 100 г дестиллированной воды.composition: 400 g of ammonium phosphate or 500 g of trisodium phosphate, 500 g of sulfuric acid and 100 g of distilled water.
При плотности тока 10 А1дм и температуре ванны 55-65° С детали обрабатываютс в течение 10 минут; при этом совершенно неочищенна новерхность нержавеющей стали приобретает гл нец.With a current density of 10 A1dm and a bath temperature of 55-65 ° C, parts are processed for 10 minutes; at the same time, the completely non-refined stainless steel surface acquires a high gloss.
Предмет изобретени Subject invention
Способ электрохимического полировани металлов, например нержавеющей стали, в сернокислотной ванне, отличающийс тем, что электрополирование производ т в ванне, содери-сащей серную кислоту и около 400-500 г/уг аммонийфосфата или тринатрийфосфата.A method of electrochemical polishing of metals, for example, stainless steel, in a sulfuric acid bath, characterized in that the electropolishing is carried out in a bath containing sulfuric acid and about 400-500 g / kg of ammonium phosphate or trisodium phosphate.
