Description

Изобретение относитс  к способам нанесени  гальванических покрытий на издели  сложного профил . Известные подобные способы, также предусматривающие применение непровод щих экранов, не обеспечивают возможности получени  размерных и защитно-декоративных покрытий на различных поверхност х одного издели . Дл  устранени  этого недостатка предлагаетс  обрабатываемые в электролитической ванне издели  помещать в закрытый непровод щий ток экран, снабженный непровод щими трубками и отверсти ми, при помощи которых осуществл ют дозирование тока.The invention relates to methods for electroplating coatings on articles of a complex profile. Known similar methods, also involving the use of non-conductive screens, do not provide the possibility of obtaining dimensional and protective and decorative coatings on different surfaces of a single product. In order to eliminate this drawback, it is proposed to place the articles processed in the electrolytic bath into a closed non-conducting current screen provided with non-conducting tubes and openings with which the current is metered.

На чертеже лредставлена ванна дл  нанесени  гальванических покрытий предлагаемым способом.In the drawing, an electroplating bath is provided by the proposed method.

Экран 1 представл ет собой разъемную пластмассовую коробку, внутри которой расположены обрабатываемые издели  2. Перхлорвиниловые трубки 3 предназначены дл  подачи электролита и подвода тока к впутренним поверхност м изделий 5, а дозирующие отверсти  4 служат дл  подачи электролита и подвода тока к наружным поверхност м изделий. Дл  облегчени  стока электролита в нижней части экрана имеютс  трубки 5. В верхней части экрана имеетс  кювета 6, заполн ема  электролитомПредлагаемый способ позвол ет успещно хромировать глухие резьбовые отверсти  на глубину 1-1,5 диаметра и гладкие отверсти  на глубину 2-2,5 диаметра. Минимально допустимый диаметр отверсти  равен 5 мм.The screen 1 is a detachable plastic box inside which the workpiece 2 is located. Perchlorvinyl tubes 3 are designed to supply electrolyte and supply current to the intrinsic surfaces of products 5, and metering ports 4 serve to supply electrolyte and supply current to external surfaces of products. To facilitate electrolyte drainage, there are tubes 5 in the lower part of the screen. In the upper part of the screen there is a cuvette 6 filled with electrolyte. The proposed method allows for solid chrome-plated threaded holes to a depth of 1-1.5 diameters and smooth holes . The minimum allowable hole diameter is 5 mm.

Предмет изобретени Subject invention

Способ нанесени  гальванических покрытий на поверхности детали при помощи наход щегос  под током электролита, отличающийс  тем, что, с целью обеспечени  равномерности покрытий, заданногоThe method of electroplating on the surface of the part using an electrolyte under the current, characterized in that, in order to ensure the uniformity of the coatings,

распределени  толщины, а также одновременного нанесени  на различные поверхности одной и той же детали размерных и защитно-декоративных покрытий, обрабатываемые детали помещают в закрытый непровод щий ток экран, а ток со стороны электролита дозируют через отверсти  в| экране и непровод щие трубки, заполненные электролитоМdistributing the thickness and simultaneously applying dimensional and protective decorative coatings to different surfaces of the same part, the workpieces are placed into a closed non-conducting current screen, and the current from the electrolyte side is metered through the holes in | screen and non-conductive tubes filled with electrolyte
