1. Shot peening: a kind of surface treatment. According to the need, a steel ball with a certain diameter is sprayed on the surface of the part to form a uniform small pit, and the chain is improved.
Surface fatigue strength.
2. Blue: After the parts are heated to a certain temperature, they are cooled by a chemical aqueous solution and saponified to make the surface color of the parts appear blue. After blue treatment
The chain looks beautiful and has a rust-proof effect. The downside is that these chemical aqueous solutions cause great pollution to the environment.
3. Phosphating: The part is immersed in a phosphating solution at a certain temperature to form a phosphating layer on the surface of the part, so that the surface color of the part is black or gray.
Improve the aesthetics of the chain while achieving the purpose of anti-corrosion. These phosphating solutions can be recycled and have less environmental pollution.
4. Nickel plating: The method of spot plating or electroless nickel plating is adopted to form a nickel plating layer on the surface of the part, and the nickel plating layer can be both beautiful chain and anti-corrosion. Nickel plated chain
Articles are generally used in open spaces.
5, galvanizing: using electroplating or electroless galvanizing method, forming a galvanized layer on the surface of the part, the galvanized layer can be beautiful chain and anti-corrosion. Nickel plated chain
Articles are generally used in open spaces.
6. Heat treatment: In the heat treatment equipment, various auxiliary media are used at high temperature to improve the structural structure of the parts and improve various physical properties.
7. Carburizing: After the parts are placed in the heat treatment equipment and heated to a certain temperature, they are kept for a certain period of time, and then the carbon-containing medium is introduced to infiltrate the carbon into the surface of the part.
One improves the hardness and wear resistance of the chain.
8. Quenching: After the parts are placed in the heat treatment equipment and heated to a certain temperature, they are kept warm for a certain period of time, and then cooled in different media according to requirements.
And improve the hardness of the parts.
9. Tempering: After passing through the quenched parts, the parts are heated at a certain temperature in the heat treatment equipment, and then kept warm for a certain period of time. Parts can be tempered
To reduce the quenching hardness, eliminate the quenching stress and improve the toughness.
10. Oiling: The oil on the chain can prevent the chain from rusting and is more lustrous.
11, grease: chain grease can prevent the chain from rusting, and more lustrous. (It is inconvenient to oil during maintenance, use grease)
12, stainless steel "target=_blank> stainless steel: no oil grease, clean and hygienic. Used in the food industry.
