CE Certified Corrosion Resistant Impeller Wheel For Industrial Fans Amorphous Nickel-Phosphorus Coated Centrifugal Fan Accessories

Corrosion Resistant Impeller Wheel for Industrial Fans Amorphous Nickel-Phosphorus Coated Centrifugal Fan Accessories

The corrosion and wear of fan impeller is mainly caused by corrosion and stress corrosion caused by corrosive gas in the fan conveying medium. The types of corrosion caused by different transport media are also different. In order to prevent corrosion and impeller corrosion and wear, the following measures are usually adopted: stainless steel with strong corrosion resistance is used as impeller material; Coating or spraying anti-corrosion layer on the surface of the impeller and improving the surface quality of the impeller to solve the corrosion and wear problem.
Amorphous nickel-phosphorus (Ni-P) alloy plating is a relatively successful surface anti-corrosion coating method. Due to the ideal amorphous structure and the alloy characteristics of the coating, the grain boundary corrosion and grain boundary defects are avoided. The Ni-P alloy with a coating hardness of HRC50-70 has strong corrosion resistance, wear resistance, and corrosion resistance to hydrochloric acid, sulfuric acid, phosphoric acid and caustic soda.

The surface of fan impeller is coated with amorphous nickel-phosphorus (Ni-P) alloy as a good corrosion resistance process.
