What Is the Carbonization and Nitriding Process When Using Car Bottom Furnace

When we talk about the carbonization and nitriding process when using car bottom furnace, we will talk the operaiton method and purpose as below:

Carbonization Process

Operation method: Place the steel part in the carburizing medium, heat it to 900-950 degrees and keep it warm, so that the steel part can obtain a certain concentration and depth of carburizing layer on the surface.

Purpose: To improve the surface hardness, wear resistance, and fatigue strength of steel components, while maintaining the toughness of the core.

Application points: 1. Used for low carbon steel and low alloy steel parts with carbon content of 0.15%~0.25%, generally with a carburizing layer depth of 0.5~2.5mm; 2. After carburizing, quenching must be carried out to obtain martensite on the surface in order to achieve the purpose of carburizing.

What Is the Carbonization and Nitriding Process When Using Car Bottom Furnace

Nitriding Process

Operation method: Utilize the active nitrogen atoms decomposed from ammonia gas at 5. -600 degrees Celsius to saturate the surface of the steel with nitrogen and form a nitride layer.

Purpose: To improve the hardness, wear resistance, fatigue strength, and corrosion resistance of steel surfaces.

Application points: It is mainly used for medium carbon alloy structural steel containing alloy elements such as aluminum, chromium, molybdenum, as well as carbon steel and cast iron. The depth of the nitride layer is generally 0.025-0.8mm.
