General Information Brief Process Description PROCESS Racking Cleaning Etching Neutralizing Anodizing Electrolytic Pigmentation Sealing Electrodeposition Coating Baking Unracking DESCRIPTION Mounting material to be treated on a frame. Removing oil and stains from the material. Dipping the material in a caustic soda solution to form a smooth surface thereon. Removing from the material surface the smut produced by etching. Applying an electric current to the material as an anode in an electrolyte to form an oxide film. Applying an electric current to the material in an electrolytic pigmentation solution containing a metal salt so that the metal salt may be absorbed into the fine pores of the oxide film to develop color. Improving the corrosion resistance and physical properties of the porous film formed by anodizing. Improving the corrosion resistance and physical properties of the porous film formed by anodizing. Heating the coating and film at a high temperature to harden it. Removing the surface treated material from the frame. Effective Date: May 23, 2024 | GI-1000-07 Page-9
