Carburizing and its function
1. What is carburizing
Carburizing is a heat treatment technology that immerses low-carbon steel or low-alloy steel in a furnace containing high-carbon gas, and at high temperatures, the high-carbon gas penetrates into the surface of the steel, thereby increasing the carbon content of the steel. There are two types of carbon sources commonly used in carburizing: gas and liquid.
2, the role of carburizing
1. Improve the hardness and strength of steel: Carburizing can increase the carbon content of steel, and since carbon is the main strengthening element in steel, it can improve the hardness and strength of steel. During the carburizing process, the high-carbon gas forms a layer of high hardness and strength on the surface of the steel, which is very useful for those mechanical parts that require high strength and hardness.
2. Improve the wear resistance of steel: Carburizing can form a super-hard permeability layer on the surface of the steel, which greatly improves the wear resistance of the steel. This is useful for mechanical parts that need to be used for long periods of time or that are rubbed a lot.
3. Improved machinability of steel: Carburizing improves the machinability of steel, making it easier to cut and machine. This reduces production costs and increases the economic efficiency of the steel.
4. Enhance the toughness of the steel: Carburizing can increase the carbon content of the steel, thereby improving the toughness and impact resistance of the steel. This is useful for structural parts that require high toughness and impact resistance.
5. Improve the service life of steel: Since carburizing can improve the hardness, strength, wear resistance and toughness of steel, it can greatly improve the service life of steel. This is very important for mechanical parts that need to be used for a long time.
3. Conclusion
Carburizing is a very common steel treatment technique that increases the carbon content on the surface of the steel, thereby improving the hardness, strength, wear resistance, toughness and longevity of the steel. Carburizing also improves the processability of steel and increases its economic efficiency. Carburizing is a very important technology in a wide range of applications in industries such as machining, automotive manufacturing, and aerospace manufacturing.
