What is the difference between electrophoresis and anodizing

Electrophoresis is equivalent to applying a layer of resin paint to the metal surface. And anodic oxidation is to use electrochemical method to make the surface metal aluminum and oxygen react to form a protective film, the surface has a metallic texture, and the grade is higher. Electrophoresis effect will be better if oxidation is done first. Anodic oxidation: anodic oxidation, electrochemical oxidation of metal or alloy. Aluminum and its alloys are a process in which an oxide film is formed on an aluminum product (anode) under the action of an applied current under the corresponding electrolyte and specific process conditions. Anodizing, if not otherwise specified, usually refers to sulfuric acid anodizing. In order to overcome the defects of aluminum alloy surface hardness, wear resistance, etc., expand the scope of application, and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloys, and anodic oxidation technology is currently the most widely used and most successful. of. Electrophoresis: Under the action of an electric field, the charged particles move toward the opposite electrode, which is called electrophoresis (electrophoresis, EP). The technique of using charged particles to move at different speeds in an electric field to achieve separation is called electrophoresis.
