(54) СПОСОБ ХИМИЧЕСКОГО НИКЕЛИРОВАНИЯ ДЕТАЛЕЙ Изобретение касаетс нанесени химических никелевых покрытий. Известен способ химического никелирова- ни с корректировкой с регенерацией раство ра путем добавлени водных растворов солей никел и гипофосфита натри н удалени из раствора ионов фосфита посредством осаж дени их сернокислым железом или гидроокисью кальци . Однако при указанном способе трудно поддерживать концентрацию ионов никел и гипофосфита в заданных пределах. Кроме того , происходит накопление анионов хлора или сульфатов, что отрицательно вли ет на процесс. Целью изобретени вл етс возможность длительного использовани раствора при сохранении посто нной концентрации его компонентов . Это достигаетс тем, что ионы никел ввод т путем электрохимического растворени никелевых анодов посто нным током, величину и периодичность включени кото:рого регулируют в зависимости от изменени рН раствора, а гипофосфит кальци вво- д т в количестве 4-6 г/л при пропускании :1 а «час. Цепь замкнута между никелевым анодом и катодом, в качестве которого может быть использован корпус ванны. Д составл ет 0,5-1,5 а/дм Отношение «лошадей элоктродов S : S ° (4-7) г 1, температура -25-50 С. Включение тока производитс при снижении рИ до нижнего допусти.-юго предела, а выключение - при достижении рМ верхнего предела. При этом можно поддерживать заданную концентрацию ионов никел и гипофосфита в растворе, так как она зависит от рН раствора. Количество никел , растворенного с ано- ,дов, пр мо пропорционально количеству элек .тричества, продушенного через электроды, а по количеству последнего определ ют количество гипофосфит-иона, необходимое пик(54) METHOD OF CHEMICAL NICKELING OF DETAILS The invention concerns the application of chemical nickel coatings. The known method of chemical nickel plating with the solution regeneration by adding aqueous solutions of nickel and hypophosphite salts of sodium and removing phosphite ions from the solution by precipitating them with iron sulfate or calcium hydroxide. However, with this method it is difficult to maintain the concentration of nickel and hypophosphite ions within the specified limits. In addition, chlorine or sulfate anions accumulate, which adversely affects the process. The aim of the invention is the possibility of long-term use of the solution while maintaining a constant concentration of its components. This is achieved by the fact that nickel ions are introduced by electrochemical dissolution of nickel anodes with a constant current, the amount and frequency of which is controlled depending on the change in the pH of the solution, and calcium hypophosphite is introduced in an amount of 4-6 g / l. : 1 a “hour The circuit is closed between the nickel anode and the cathode, which can be used as the body of the bath. D is 0.5-1.5 a / dm. The ratio of the horses of the eloctrodes S: S ° (4-7) g 1, temperature -25-50 C. The current is switched on when the pI is lowered to the lower tolerance. and off when the pM reaches the upper limit. In this case, it is possible to maintain a given concentration of nickel and hypophosphite ions in the solution, since it depends on the pH of the solution. The amount of nickel dissolved from the anodes is directly proportional to the amount of electricity flowed through the electrodes, and the amount of the hypophosphite ion, the required peak, is determined by the amount of the latter.
