Carburizing, Carbonitriding, Nitriding & Nitrocarburizing in CNC Machining Industry

What is Carbonitriding?

Carbonitriding is a thermochemical process that involves the diffusion of both carbon and nitrogen into the surface of a part. The process is typically carried out in a furnace, where the part is heated to a specific temperature in the presence of a carbon and nitrogen-rich atmosphere. The length of time and temperature that the part is exposed to the atmosphere will determine the depth and composition of the resulting carbonitrided layer.

Benefits of Carbonitriding

Carbonitriding offers a number of benefits for CNC machined parts, including:

• Increased Wear Resistance – The carbonitrided layer that forms on the surface of the part is extremely hard and wear-resistant, making it ideal for high-wear applications.
• Improved Fatigue Strength – The carbonitrided layer also improves the fatigue strength of the part, making it more resistant to cracking and other forms of failure.
• Improved Corrosion Resistance – Carbonitriding also improves the corrosion resistance of a part, helping to protect it from environmental factors such as moisture and chemicals.
• Improved Surface Hardness – The carbonitrided layer also increases the surface hardness of the part, which can improve its overall strength and durability.

Applications of Carbonitriding in CNC Machining

Carbonitriding is a widely used surface treatment process in the CNC machining industry, particularly in applications where high wear resistance and durability are critical. Some of the most common applications of carbonitriding in CNC machining include:

• Gears and Gear Components – Carbonitriding is commonly used to improve the wear resistance and fatigue strength of gears and gear components.
• Machine Components – Carbonitriding can be used to improve the wear resistance and corrosion resistance of various machine components, including shafts, bearings, and housings.
• Tooling – Carbonitriding is often used to improve the durability and wear resistance of various cutting and forming tools used in CNC machining, such as punches, dies, and drills.
• Automotive Components – Carbonitriding is commonly used in the automotive industry to improve the durability and wear resistance of various components, including engine and transmission parts.

Conclusion

Carbonitriding is a valuable surface treatment process that offers a number of benefits for CNC machined parts. With improved wear resistance, fatigue strength, and corrosion resistance, carbonitriding is ideal for high-wear applications and critical machine components. By choosing carbonitriding as a surface treatment option, CNC machining manufacturers can ensure that their parts are durable, reliable, and long-lasting.
