Description
Известный cnocoi6 электролитического осаждени паллади из электролита на основе соли паллади , сульфата аммони , сахарина имеет тот недостаток, что покрыти не блест щие и имеют пониженную износостойкость. По предложенному способу электролитического осаждени паллади дл повышени износостойкости и улучшени качества покрыти в электролит ввод т этанол амин при следующем соотношении компонентов, г/л: Комплексна соль паллади The known cnocoi6 electrolytic deposition of palladium from an electrolyte based on a palladium salt, ammonium sulfate, saccharin has the disadvantage that the coatings are not shiny and have a reduced wear resistance. According to the proposed method of electrolytic deposition of palladium, ethanol amine is introduced into the electrolyte in order to increase wear resistance and improve the quality of the coating in the following ratio of components, g / l: Complex palladium salt

и процесс ведут при 20-30°€ и катодной плотности тока 0,3-1,6 а/дм. Электролит готов т следующим образом. К раствору комплексной соли паллади при перемешивании добавл ют этанол амин, затем сульфат аммони и сахарин. После полного растворени компонентов раствор фильтруют и получают готовый электролит блест щего палладировани желтолимонного цвета.and the process is carried out at 20-30 ° € and a cathode current density of 0.3-1.6 a / dm. The electrolyte is prepared as follows. With a stirring, ethanol amine is added to the solution of the palladium complex salt, then ammonium sulfate and saccharin. After complete dissolution of the components, the solution is filtered and the finished electrolyte of a brilliant palladium of yellow-colored color is obtained.
Электролит стабилен в работе, имеет катодный выход по току 97--98Vo.The electrolyte is stable in operation, has a cathode current output of 97--98Vo.
По это-му способу на цветных металлах, .например медь, латунь, серебро, осаждают блест щие палладиевые покрыти толщиной от 0,5 до 30 мк в довольно широком интервале катодных плоскостей тока.By this method on non-ferrous metals, for example, copper, brass, silver, brilliant palladium coatings with a thickness of 0.5 to 30 microns precipitate in a fairly wide range of cathode current planes.
