Description

The present invention takes up the field of metal processing technology, and specifically is a metal coating device.

Metal coating means coating the surface of a metal such as steel with another metal. The metal coating aims to improve the functions and characteristics that the base metal lacks. Specifically, it includes improvement of anticorrosion / corrosion resistance, improvement of decorativeness, improvement of hardness (scratch resistance), improvement of wear resistance, improvement of electrical characteristics, improvement of adhesion to solder and the like. Electroplating is a type of metal coating, and generally, a target metal is immersed in a solution containing a salt of the metal to be coated, and a cathode current is passed through the coating metal as an anode. In this method, the electrolytic bath does not flow and electroplating is performed by the natural movement of electrons, so the coating speed becomes slow, and the quality of the plating layer and the precipitation rate often decrease due to the non-uniformity of the concentration of the electrolytic bath. Furthermore, in the process of electroplating, oxygen and hydrogen are produced, but since the gas collecting device is not installed in the conventional coating device, gas resources are wasted. The present invention is an apparatus capable of solving the above problems.
