Discontinuous ultrasonic electroplating device and application thereof

Abstract

The invention relates to field of electroplating and in particular relates to a discontinuous ultrasonic electroplating device and an application thereof, and the discontinuous ultrasonic electroplating device can be applied to the electroplating process of various electroplating industries, such as Ni electroplating, Cr electroplating, Cu electroplating or Mn electroplating. The discontinuous ultrasonic electroplating device comprises an ultrasonic sink, a water bath, an electroplating container, an ultrasonic generator and a controller, wherein the ultrasonic sink is put in water to form the water bath, the electroplating container is filled with a plating solution, the electroplating container is put in the ultrasonic sink, the water surface of the ultrasonic sink outside the electroplating container is level with or lower than the height of the liquid level of the plating solution, and the lower part of the electroplating container has a distance from the ultrasonic sink. The bottom of the ultrasonic sink is provided with the ultrasonic generator, the output end of the controller is connected with the ultrasonic generator, and the input end of the controller is connected with a time relay. According to the invention, the problem that hard ultrasonic electroplating films are too thick and fragile is solved, and the bottleneck on enhancing all the performance in the common electroplating industry is correspondingly broken. The abrasive resistance, corrosion resistance and film binding force of the film are obviously enhanced as compared with those of the ultrasonic electroplating film.

Description

technical field [0001] The invention relates to the field of electroplating devices, in particular to a discontinuous ultrasonic electroplating device and its application, which can be applied to electroplating processes in various electroplating industries, such as electroplating Ni, Cr, Cu or Mn. Background technique [0002] In the past two decades, due to the popularization of ultrasonic equipment and the wide application of sonochemical reactors, the application research of ultrasonic in chemistry, chemical industry and new materials has developed rapidly, and formed an interdisciplinary subject - sonochemistry. Ultrasound is applied to electroplating, and there are many patents abroad, especially in Japan, followed by the United States, Russia, the European Union, and India. There are more and more researches in this area in our country. At present, there are already industrial-scale ultrasonic generating equipment on the market, which has laid the foundation for the a...
