What is electroplating?


Electroplating (Electroplating) is a method in which an object that conducts electricity is placed in a solution in which the metal to be plated is dissolved, and the metal in the solution is reduced by electrolysis to form a thin metal film on the surface of the object. The advantage is that the plating speed is fast, thick plating is possible, and it is possible to control the plating film thickness and the alloy ratio of alloy plating with the amount of electricity.
At our company, we perform precious metal plating such as platinum (Pt), gold (Au), and palladium (Pd). It is also used for electrodes due to its characteristics, durability, and safety. In particular, for the titanium electrode plates used in alkaline ion water purifiers, the technology of directly plating platinum (Pt) on the titanium material, which is our specialty, is adopted, and our long-term experience is backed by our plating technology.
