1. Different processing methods
Electroplating uses the electroplating aluminum material as the cathode, which is the same as the electroplated metal as the anode. The electrolyte is a solution containing metal ions for electroplating, and an affirm current is input between the anode and the cathode. The plating material and the material to be plated are two different materials. For example, beryllium copper plate with nickel, beryllium copper is the substrate, and nickel is the plating layer.
Anodization uses chemical or electrochemical treatment to produce a thin film layer on the surface. The processed material acts as an anode, and when electricity is applied in a specific electrolyte, a thin film will be formed on the surface. If the aluminum alloy is oxidized, an aluminum oxide film will be formed on the surface of the workpiece. Alumina is chemically stable, will not be oxidated or corroded by acid, and can be dyed into various colours.
2. Different processing objects
The objects processed by the electroplating method are mainly metal or non-metal. The most commonly used plating metals are nickel, chromium, tin, copper, silver, and gold. Often referred to as nickel plating, chrome plating, gold plating, etc.
Anodizing is a method of metal surface treatment. Most metal materials (such as stainless steel, zinc alloy, aluminum alloy, magnesium alloy, copper alloy, titanium alloy) can be anodizing in a suitable electrolyte.
3. Different processing principles
Electroplating uses the electroplating material as the cathode. Anodizing uses the material to process as the anode.
Electroplating is due to the charge effect, the metal anode ions move to the cathode, where the electrons deposit on the material to the plating. At the same time, the metal in the anode dissolves, constantly replenishing the metal ions in the electrolyte.
