ИзОбретение относитс  к области нанесени  металлических тюкрытий.The invention relates to the field of deposition of metallic coverings.

Известен снособ химического осажденн  металлов нз раствора, содержащего соеднненне осаждаемого металла и восстановитель.Known chemical chemical precipitated metals nz solution containing the metal to be deposited and the reducing agent.

Предлагаемый способ отличаетс  от известного тем, что в Качестве соединени  осаждаемого металла и восстановител  нснользуют нерренат аммонн  и формальдегндсульфокснлат соответственно нри определенном нх соотношенни н ироцесс провод т при онределенном режиме. Это обеспечивает осаждение ренн .The proposed method differs from the known one in that as a compound of a metal to be deposited and a reducing agent, the ammonium and formaldehyde sulfoxnlate ammonium nitrates are used, respectively, at a certain nx ratio, and the process is carried out under a definite mode. This provides precipitation renn.

Суидность предлагаемого снособа заключаетс  В том, что поверхность изделий обрабатывают раствором, содержащим, г/л:Suedness of the proposed removal method is that the surface of the products is treated with a solution containing, g / l:

Перренат аммоии 7-15Ammonium perrenate 7-15

Формальдегндсульфо.ксилат 5- 8, нри 40-80°С и рН 2,5-4,5.Formaldegndsulfo.xylate 5-8, at 40-80 ° C and pH 2.5-4.5.

Кроме иеррената аммони  нснользуюг также лерренат щелочного металла. рН раствора довод т до заданного значени  нутем добавлени  сериой кислоты.In addition to ammonium ierrenate, alkali metal lerrenate is also nsnoljuig. The pH of the solution is adjusted to the desired value with the addition of seric acid.

При М е р. Медные издели  погружают з раствор, содержащий, г/л: - When Mer. Copper products immerse s solution containing, g / l: -

Перренат аммони .7Ammonium perrenate .7

Формальдегидсульфо-ксилат8Formaldehyde sulfo-xylat8

Проиесс осаждени  провод т нри 55°С н рН 2,5 в течение 20 мин. Плотность загрузки составл ет 5 дм-/л. В результате на поверхностн нзделпй получакп пленку ренн  толщиной ОКО.Ю 1 МК.The precipitation process is carried out at 55 ° C and pH 2.5 for 20 minutes. The loading density is 5 dm / l. As a result, on the surface poluchakp film renn thickness OKO.Yu 1 MK.

Раствор, нснользхемый но нредлагаемому способу, стабилен в работе н пригоден дл  многократного иснользовани  с предварительной фпльтраннсй, корректировкой рП и концентрации комнонентов.The solution, which is unsuitable for the proposed method, is stable in operation and is suitable for repeated use with preliminary plasticization, correction of RP and concentration of components.

Предмет изобретени Subject invention

Способ хнмцческого осаждени  металлов из раствора, содержащего соединение осаждаемого металла и восстановитель, огличаюгцпйс  тем, что, с целью осажденн  рени , в .качестве соединени  осаждаемого металла и восстановител  используют иерренат аммонн  и формальдегидсульфоксилат соответствен) о при следующем соотношении комнонентов, г/л:The method of chemical precipitation of metals from a solution containing a compound of a deposited metal and a reducing agent is confused by the fact that, for the purpose of precipitated rhenium, the quality of the compound of the deposited metal and the reducing agent uses amrenn and formaldehyde sulphoxylate, respectively, in the following ratio of components, which is used by the ammunn and formaldehyde sulphoxylate).

.Перренат- аммонн 7-15Perrenat-ammonium 7-15

Формальдегндсульфоксилат 5-8 и процесс ведут нри 40-80°С и рП 2,5-4,5.Formaldegne sulphoxylate 5-8 and the process is carried out at 40-80 ° C and RP 2.5-4.5.
