Изобретение относитс  к способам контрол  толщины гальванических покрытий, в частности марганцевых покрытий.This invention relates to methods for controlling the thickness of electroplated coatings, in particular manganese coatings.

Известен химический способ Контрол  толщины , например гальванических медных покрытий путем химического растворени  участков покрыти .A known chemical method is to control the thickness, for example, electroplating copper coatings by chemical dissolution of the coating areas.

Дл  определени  толщины марганцевых покрытий предлагаетс  способ, по которому на поверхность покрыти  нанос т раствор соли аммони .To determine the thickness of manganese coatings, a method is proposed by which a solution of ammonium salt is applied to the surface of the coating.

На поверхность марганцевого покрыти  можно наносить раствор соли хлористого или сернокислого аммони  с концентрацией 70- 100 г/л в пересчете на ион аммони .A solution of a salt of ammonium chloride or ammonium sulphate with a concentration of 70-100 g / l in terms of ammonium ion can be applied to the surface of the manganese coating.

Способ реализуют, например, следующим образом.The method is implemented, for example, as follows.

На поверхность детали последовате.аьно нанос т капли раствора, содержащего 300 г/л хлористого ам1мони . Капл  выдерживаетс  на поверхности в течение 30 сек. Раствор хлористого ам,монй  нанос т на поверхность покрыти  до его полного сн ти .Drops of a solution containing 300 g / l of ammonium chloride are deposited on the surface of the part successively. The droplet is kept on the surface for 30 seconds. A solution of ammonium chloride was applied to the surface of the coating until it was completely removed.
