SURFACE FINISHING
Anodizing
Anodizing is the process of developing a layer of aluminum oxide (Al2O3) on the surface of the aluminum and its alloys through the electrolysis process.
Introduction
Anodizing is the process of developing a layer of aluminum oxide (Al2O3) on the surface of the aluminum and its alloys through the electrolysis process. After anodizing, the surface becomes super resistive to corrosion and enhances the other mechanical properties of wear resistance and hardness. Various colors such as, black, blue, gold, grey, and red are easily achievable with the anodizing process. It can maintain a surface roughness not lower than Ra 3.2μm.
It is used in various industries, including automobile, architecture, aerospace, home appliances, etc.
