Ningbo Gaoxin Electroplating Co., Ltd. specializes in providing anodizing treatment business

2020-11-03

Anodizing is one of the methods of metal surface treatment. A material protection technology in which the metal material used as the anode forms a film on the surface of the metal material by applying an electric current in a specific electrolyte. Most metal materials (such as stainless steel, zinc alloy, aluminum alloy, magnesium alloy, copper alloy, titanium alloy) can be anodized in a suitable electrolyte.

Through the anodic oxidation treatment, it can give the metal material surface beautiful appearance, good corrosion resistance, wear resistance, insulation and other functions, so as to meet different design requirements.

At present, anodizing treatment of aluminum is widely used. Because the aluminum oxide film has a fine structure, good adsorption, and is not easy to fall off, it is coated with a fine oxide film through anodizing process to protect it from continuous oxidation.

There are many kinds of anodizing processes for aluminum, including ordinary anodizing, hard anodizing, and ultra-low temperature hard anodizing. Especially hard anodizing treatment is widely used in pistons, cylinders, cylinder linings, hydraulic machines and turbines, steam valves, gears, gun parts, clutches, brake discs and other hard, wear-resistant and highly corrosion-resistant aluminum alloy parts On the surface treatment.

The anodizing treatment of aluminum is to form an oxide film on the surface of aluminum metal by the action of electric current, which is hard and wear-resistant, has high corrosion resistance and beautiful color. The aluminum alloy itself is easy to process, high in strength, and has a wide range of uses. The products are aluminum doors and windows, furniture, cameras and instrument housings. Aluminum manufacturing and its processing industry is also expanding day by day, and aluminum anodizing equipment processing has considerable market potential.

The development of anodic treatment, such as hardanodizing, also uses AC and DC anodic treatment at low temperature. This hardened anodized aluminum can be used for pistons, cylinders, cylinder linings, hydraulic and turbine parts, steam valves, gears, gun parts, clutches, brake discs, (brakedisk), machines and tools Wait. Bath temperature, current density.
