What are anodizing and anodizing? What is the difference between anodizing and anodizing
For the use of magnesium anode, aluminum anode, I believe you should have a certain understanding of the anode material is mainly forced current cathodic protection, sacrificial anode protection law and other metal corrosion important raw materials. In order to improve the efficiency of the anode, we need to constantly improve the performance of the anode. From a large number of research data, we found that through electroplating can improve the performance of the anode, but do you know what electroplating and anodizing refers to, the difference between anodizing and oxidation, how much understanding
Anodic electroplating and anodic oxidation electroplating is to cover other corrosion resistant metal objects on the anodic products through electrolysis, or through the direct current action on the electroplating solution to make the electrode of the anodic material electrochemical changes. After anodic plating, the material on the cathode gets electrons to be reduced, forming a coating on the cathode; The material on the anode loses electrons and is oxidized, and the material on the anode goes into the bath.
Anodic oxidation is to add high voltage direct current in the anodic oxidation solution to make oxygen and other oxidizing substances produced on the anodic surface oxidize the anode itself, resulting in a dense oxide surface, so it has corrosion resistance. The difference between anodizing and oxidation, connection between electroplating appearance is electroplated metal color, and anodizing can change the color of the metal surface, such as zinc anodizing into gold, red and other colors. Electroplating is a kind of cathode treatment, the parts as a cathode, the surface adsorption anode metal ions, forming a coating; Anodic oxidation is the part as the anode, let itself oxidation, the formation of oxidation layer, electroplating and anodic oxidation can play a role in corrosion resistance.
