Bearing forgings are key components in mechanical equipment, which need to have high hardness and wear resistance to ensure the normal operation and service life of the equipment. The surface treatment and protection of bearing forgings is an important means to improve its performance and service life. This paper will introduce the surface treatment and protection technology of bearing forgings.
Bearing forgings surface treatment
Heat treatment: Heat treatment is one of the important means of surface treatment of bearing forgings, through heating, insulation and cooling processes, change the structure and performance of the surface of the forgings, improve its hardness and wear resistance. Commonly used heat treatment methods are quenching, tempering and so on.
Chemical treatment: Chemical treatment is to modify the surface of bearing forgings through chemical reactions to enhance its corrosion resistance, oxidation resistance and other properties. Common chemical treatment methods include bluing, nitriding and so on.
Electroplating: Electroplating is to deposit a layer of metal film on the surface of bearing forgings to improve its surface hardness and wear resistance, while enhancing its corrosion resistance. Common electroplating methods are chrome plating, zinc plating and so on.
Protection of bearing forgings
Coating: Coating a layer of coating on the surface of bearing forgings can isolate the contact between air, moisture and other corrosive media and the surface of the forgings, and play a protective role. Commonly used coatings are paint, anti-rust oil and so on.
Physical protection: Using physical methods, such as spraying, dipping, brushing, etc., to form a dense protective film on the surface of bearing forgings to prevent the erosion of corrosive media on the surface of forgings.
A bearing manufacturing enterprise adopts a surface treatment method combining heat treatment and chemical treatment for bearing forgings, which effectively improves the hardness and wear resistance of forgings and prolongs the service life of bearings. At the same time, the company also uses the combination of paint coating and physical protection, which effectively prevents the erosion of the corrosive medium on the surface of the forging, and improves the reliability and stability of the bearing.
Surface treatment and protection of bearing forgings is an important means to improve its performance and service life. By using appropriate surface treatment and protection technology, it can effectively improve the hardness and wear resistance of bearing forgings, enhance their corrosion resistance, extend the service life of bearings, and create greater economic and social benefits for enterprises.
