Does the heavy metal solution dilute with the support electrolyte?
Why plating can be plated, that is, through electrolysis, so that the solution of metal ions precipitation, and even attached to the workpiece. This is by far the most common way.
Plating (Electroplating) process is to use the principle of electrolysis plating on a thin layer of metal or alloy in some metal surface, is the process of making the surface of metal or other material parts attached to a layer of metal film by electrolysis so as to prevent metal oxide (rust), improve wear resistance, electrical conductivity, reflection, corrosion resistance (copper sulfate) and improves the appearance effect. The outer layers of many coins are also electroplated.
When plating, the coating metal or other insoluble material is used as an anode, the workpiece to be plated is used as the cathode, and the cation of the coating metal is reduced to form a coating on the surface of the workpiece to be plated. In order to eliminate the interference of other cations and make the coating even and solid, the solution containing the coating metal cation is used as the electroplating solution so as to keep the concentration of the metal cation of the coating unchanged. The purpose of electroplating is to deposit a metal coating on the substrate to change the surface properties or sizes of the substrate. Electroplating can enhance the corrosion resistance of metal (coating metal uses corrosion resistant metal), increase hardness, prevent wear, improve conductivity, smoothness, heat resistance and surface beauty.
