What are the surface treatment methods of copper ring forging?

The surface treatment method of copper ring forging is of great significance to improve its corrosion resistance, wear resistance and aesthetics. This paper introduces several common surface treatment methods for copper ring forging.

Shot peening

Shot peening is a kind of surface treatment method by blasting metal or non-metal pellets to the surface of the workpiece at high speed to remove impurities such as oxide, rust and so on, while forming a hardened layer of a certain thickness on the surface, so as to improve the fatigue resistance and wear resistance of the workpiece. Shot peening is suitable for various shapes of copper ring forgings, which can significantly improve the surface hardness and corrosion resistance.

Mechanical polishing

Mechanical polishing is a surface treatment method that polishes the surface of the workpiece through mechanical equipment such as polishing machine. Mechanical polishing can remove impurities such as rough parts and oxide skin on the surface of the workpiece, make the surface smooth, and improve the corrosion resistance and beauty of the workpiece. Mechanical polishing is suitable for various shapes of copper ring forgings, but the processing time is long and the efficiency is low.

Chemical polishing

Chemical polishing is a surface treatment method that chemically reacts with the surface of the workpiece through chemical reagents to remove impurities such as oxide and rust and make the surface smooth at the same time. Chemical polishing is suitable for various shapes of copper ring forgings, the processing time is short, the efficiency is high, but the need to use chemical reagents, there is a certain pollution to the environment.

Laser cladding

Laser cladding is a surface treatment method in which alloy powder or ceramic powder is fused to the surface of the workpiece by means of a high-energy laser beam to form a coating with high hardness, high wear resistance and corrosion resistance. Laser cladding is suitable for various shapes of copper ring forgings, the coating and the base material are closely combined, the processing time is short, the efficiency is high, but the equipment cost is high.

Spray treatment

Spraying treatment is a surface treatment method that sprays paint onto the surface of the workpiece by spraying equipment to form a protective film. Spraying treatment is suitable for various shapes of copper ring forgings, which can significantly improve its corrosion resistance and aesthetics, but it needs to use paint, which has a certain pollution to the environment.

In short, there are many surface treatment methods for copper ring forgings, including shot peening, mechanical polishing, chemical polishing, laser cladding and spraying treatment. Different surface treatment methods have different characteristics and application ranges, and appropriate surface treatment methods should be selected according to specific needs. At the same time, it is necessary to pay attention to environmental protection and worker safety in the surface treatment process.
