ИзОбретение относитс /к области наиесени покрытий, iB частности ,к юрадварителыной подготовке ло-верхности металлов перед нанесением гальваничеоких покрытий.The invention relates to the range of coatings, iB in particular, to the ideal preparation of the surface of metals before electroplating.
Из)вестен pacTiBop дл предварительной подготовки поверхности алюмини и его перед на.несением гальваничеокик покрытий, содержащий фторбораты (НИкел тл циика.From) pacTiBop is known for preliminary preparation of the surface of aluminum and its coating before the deposition of electroplating coatings containing fluoroborates (nickel plating).
Предложенный раствор отличаетс от известного тем, что в его состав введен триэтанолаэдин при определенном соотношении компононтое . Это способ ствует повышению прочности сцеплени покрытий с основой.The proposed solution differs from the well-known one in that triethanoledine is introduced into its composition at a definite component ratio. This helps to increase the adhesion strength of the coatings to the substrate.
Раствор содержит (в г/л): Фторборат иакел 120-200The solution contains (in g / l): Fluoroborate iakel 120-200

ПрОЦасс обработки предложенным раствором осуществл ют сначала химически при рН 3,7-4,4 и температуре 18-25°С в течение 20-60 сек, зате1М - электрохимичеаки .в течение 20-30 сек при катодеой плотности тока 0,5--1,5 а/дм.The treatment of the PROCass treatment with the proposed solution is carried out first chemically at a pH of 3.7-4.4 and a temperature of 18-25 ° C for 20-60 sec, then ZAT1M - electrochemical for 20-30 sec at a cathode current density of 0.5-- 1.5 a / dm
ПрИМер. Павер1Хность алюминиевых изделий последавателыно обезжиривают в органическом растворителе и -в течение 5 мин при 20°С в 5%-ном растворе еоцкого натра, а после промыики в воде 0|брабаты1вают в течение 30-60 сек IB растворе, содержащем Example. The aluminum products are subsequently degreased in an organic solvent and for 5 minutes at 20 ° C in 5% sodium hydroxide solution, and after washing in water 0 ~ brabaty for 30-60 seconds with an IB solution containing
30 г/л 50%-HO i азотной кислоты и 30 г/л фтористого алю(.30 g / l 50% -HO i nitric acid and 30 g / l aluminum fluoride (.
Далее издели промывают водой и провод т хиМическую обработку в течение 60 сек при 20°С в растворе, содержащем (в г/л): Фторборат никел 200Next, the products are washed with water and chemically treated for 60 seconds at 20 ° C in a solution containing (in g / l): Nickel fluoroborate 200

Затем издели обрабатывают в том же растворе в течение 30 сек электрохи мическп при катодной плотности тока 1,0 а/дм. После промывки водой осаждают электрохимичаскиМ способом слой никел из электролита типа Уоттса. В результате такой обработки получают покрытие, прочность оцаплен-и которого с основой составл ет 2,4 кг/мм.The products are then treated in the same solution for 30 seconds with electrochemical at a cathode current density of 1.0 a / dm. After washing with water, electrochemical clocks are precipitated by the method of nickel from a Watts type electrolyte. As a result of this treatment, a coating is obtained, the strength of which is 2.4 kg / mm.
