Electrophoresis is the formation of a uniform, dense coating on the surface of a workpiece by electrochemical means. Its coating can be made of different resin materials with corrosion resistance, wear resistance, oxidation resistance and other properties.

Electroplating is the deposition of a metallic coating on the surface of a metal to improve its corrosion resistance, electrical conductivity and beauty. Electroplating can be done with different metal materials, such as chromium plating, nickel plating, gold plating, etc.

The difference between the two is that electrophoresis forms a nonmetallic surface coating, while electroplating forms a metallic surface coating;  electrophoretic coatings may use different resin materials, and electroplating may use only metal materials;  electrophoretic coatings have some flexibility, whereas electroplated coatings are hard and brittle.

Which is better depends on different application scenarios and requirements. Electrophoresis is often a better option when corrosion resistance, wear resistance, aesthetic properties, etc. are required;  when the electrical conductivity of the metal needs to be improved, corrosion resistance, etc., electroplating is often a better option.
