Изобретение относитс  к растворам дл  пассивации поверхности нержавеющих сталей.The invention relates to solutions for passivating the surface of stainless steels.

Цель изобретени  - интенсификаци  процесса.The purpose of the invention is to intensify the process.

Состав растворов, услови  и качество обработки представлены в таблице .The composition of the solutions, conditions and quality of treatment are presented in the table.

Как видно из данных таблицы, раствор позвол ет сократить продолжительность процесса пассивации нержавеющих сталей до 1,2-1,5 мин, т.е. в 2-2,5 раза по сравнению с известным . Интенсификаци  процесса пассировани  в предлагаемом растворе приводит к быстрому формированию плотной пассивной пленки на поверхности нержавеющих сталей.As can be seen from the table, the solution reduces the duration of the process of passivation of stainless steels to 1.2-1.5 min, i.e. 2-2.5 times compared to the known. Intensification of the passaging process in the proposed solution leads to the rapid formation of a dense passive film on the surface of stainless steels.

Интенсификаци  процесса пассивировани  приводит к быстрому формированию пассивной пленки. О завершении процесса пассивировани  свидетельствует практически не измен юща с  с увел1А1ением .концентрации отходов сероочистки коксового газа в растворе величина скорости коррозии.Intensification of the passivation process leads to the rapid formation of a passive film. The completion of the passivation process is evidenced by the magnitude of the corrosion rate, which does not change with an increase in the concentration of desulphurisation of coke oven gas in the solution.

Снижение времени пассивировани  позвол ет в свою очередь повысить производительность раствора, т.е. увеличить его цикл работы в промышленной ванне.Reducing the passivation time allows in turn to increase the productivity of the solution, i.e. increase his work cycle in the industrial bath.

После обработки в предлагаемом растворе поверхность нержавеющей стали чиста , блест ща , ровна , без следов шлама.After processing in the proposed solution, the surface of the stainless steel is clean, shiny, smooth, with no traces of sludge.
