Description
Изобретение относитс к гальванотехнике и может быть использовано в процессе хромировани на токе переменной пол рности.The invention relates to electroplating and can be used in the process of chromium plating on a current of variable polarity.
Наиболее близким к предложенному по технической сущности и достигаемому результату вл етс способ стабилизации гальванического процесса на токе переменной пол рности, включающий регулирование величины тока ванны и коррекцию количества электричества , протекающего через ванну в периоды катодной пол рности, пр мо пропорционально отклонению напр жени на электродах ванны от заданного значенил. D The closest to the proposed technical essence and the achieved result is a method of stabilizing the electroplating process on a current of variable polarity, including controlling the magnitude of the bath current and correcting the amount of electricity flowing through the bath during periods of cathodic polarity, is directly proportional to the voltage deviation on the electrodes of the bath from a given value. D
Недостатком известного способа стабилизации гальванических процессов вл етс нарушение ритмичности процесса , так как при изменении состава электролита в процессе работы ванны измен етс напр жение на электродах ванны во врем катодной пол рности и измен етс длительность периодов катодной пол рности. Это приводит к изменению длительности всего гальванического процесса, состо щей из сутипиы времен катодных и анодных пол рностей. Неритмичность известного способа не позвол ет встраивать .A disadvantage of the known method of stabilization of electroplating processes is the disruption of the rhythm of the process, since when the composition of the electrolyte changes during the operation of the bath, the voltage on the bath electrodes changes during the cathode polarity and the duration of the cathode polarity changes. This leads to a change in the duration of the entire galvanic process, consisting of the essence of the cathodic and anode polarities. The irregularity of the known method does not allow embedding.
его в непрёрывный технологический процесс изготовлени изделий с жестким циклом работы, где гальваническа обработка вл етс промежуточной операцией.him in a continuous process of manufacturing products with a rigid cycle of work, where the galvanic treatment is an intermediate operation.
Цель изобретени - обеспечение ритмичности процесса.The purpose of the invention is to ensure the rhythm of the process.
Поставленна цель достигаетс тем, что в способе стабилизации гальванического процесса на токе переменной пол рности, включающем регулирование величины тока ванны и коррекцию количества электричества, протекающего через ванну в периоды катодной пол рности , пр мо пропорционально отклонению напр жени на электродах ванны от заданного значени , коррекцию количества электричества осуществл ют изменением величины катодного тока ванны в зависимости, обратно пропорциональной изменению выхода по току.The goal is achieved by the fact that in the method of stabilizing an electroplating process on a current of variable polarity, including controlling the magnitude of the bath current and correcting the amount of electricity flowing through the bath during periods of cathode polarity, is directly proportional to the voltage deviation on the electrodes of the bath from a predetermined value, the correction The amounts of electricity are made by varying the magnitude of the cathode current of the bath, depending inversely proportional to the change in current output.
Така коррекци количества электричества обеспечивает четкую ритмичность процесса, так как длительность процесса не измен етс , и,в то же врем , обеспечиваетс посто нство толщины хрома при обеднении электролита.Such a correction of the amount of electricity ensures a clear rhythm of the process, since the duration of the process does not change, and at the same time, the thickness of chromium is maintained when the electrolyte is depleted.
