Dalian metal coating

Dalian metal plastic coating of the surface modification, optimization, also known as the surface is by means of ion beam, laser, plasma, etc. New technology, change the material composition, structure and properties of surface and near surface, to obtain using traditional metallurgy and unable to get new surface treatment technology of thin layer materials, or make traditional material has better performance.

According to different USES, different materials are selected to form corrosion resistant alloys, or alloy elements are added to the metal to improve its corrosion resistance, which can prevent or slow down the corrosion of the metal. Reducing the concentration of corrosive medium, removing the oxygen in the medium, controlling the ambient temperature and humidity can reduce and prevent metal corrosion. The protected metal and another additional electrode are used as the two poles of the electrolytic cell, so that the protected metal is used as the cathode, and the cathode is protected under the action of the external direct current.

Although the corrosion of paint metal in dalian brings great harm to production, it can also use the principle of corrosion to serve production and develop the technology of corrosion processing. The principle of arc spraying coating is the combination of cathodic protection and mechanical shielding. However, due to the particularity of underground gas, gas explosion is easily caused by arc, so this technology is difficult to be applied in underground.
