If makeup mirror coating composition can be divided into a single metal coating, alloy coating and composite coating three categories.
If classified by purpose, can be divided into: ① protective coating; ② protective decorative coating; ③ decorative coating; ④ repair coating; ⑤ functional coating
Single metal plating: single-metal high-end cosmetic mirror plating has been 170 years of history, the 33 kinds of metal cosmetic mirror on the periodic table can be obtained from the electrodeposition of aqueous solution. Commonly used in electroplating zinc, nickel, chromium, copper, tin, iron, cobalt, cadmium, lead, gold, silver and other l0 species. In the cathode simultaneously deposited two or more elements of the coating formed by the alloy coating. Alloy coating with a brand of cosmetic mirror single metal mirror coating does not have the organizational structure and properties, such as amorphous Ni-P alloy, the phase diagram of each core sn alloy, and has a special decorative appearance, particularly high corrosion resistance And excellent weldability, magnetic alloy coating.
Composite plating: Composite plating is the solid particles added to the bath and metal or alloy co-deposition, the formation of a metal-based surface composites process to meet the special application requirements.
According to the electrochemical properties between the coating and the base metal classification, electroplating makeup mirror can be divided into high-grade anode coating and cathode coating two broad categories.
Where the coating metal is negative relative to the base metal potential, the formation of corrosion when the micro-cell plating as the anode, so that the anode coating, such as steel parts zinc coating; and the coating metal relative to the potential of the base metal is positive, When the formation of corrosion of micro-plating layer for the cathode, it said that the cathode coating, such as steel parts on the nickel layer and tin layer.
