Carburizing is a process used to improve the surface properties of steel parts. It enhances their hardness, wear resistance, and fatigue strength. There are several types of carburizing commonly used in the industry.
5 Key Methods Explained
1. Gas Carburizing
Gas carburizing is a case hardening process. It involves placing steel parts in a furnace with a carbon-rich atmosphere. The carbon potential is controlled by adding hydrocarbon gases like methane or propane. This increases the carbon content. The process depends on time and temperature. Higher temperatures and longer times result in a greater case thickness. Gas carburizing is typically done at temperatures around 1600°F to 1700°F.
2. Liquid Carburizing (Cyaniding)
Liquid carburizing, also known as cyaniding, is another type of carburizing process. It involves immersing steel parts in a liquid bath containing cyanide compounds. The parts are heated to a specific temperature, usually around 1600°F, and held for a certain time. The cyanide compound releases carbon and nitrogen, which diffuse into the surface of the parts. This process is commonly used for small and intricate parts.
3. Solid (Pack) Carburizing
Solid or pack carburizing is a process where steel parts are surrounded by a carbon-rich material. This material can be charcoal or carbon powder, in a sealed container. The container is then heated to a high temperature, typically around 1600°F to 1800°F. The carbon from the pack material diffuses into the surface of the parts, creating a hardened case. This process is often used for large and heavy parts.
4. Vacuum Carburizing
Vacuum carburizing is performed in a controlled atmosphere. It has precise temperature and carbon potential control. This method is ideal for maintaining the integrity of the parts.
5. Pit Carburizing
Pit carburizing is a process used for long, thin parts. The parts are suspended in a deep pit-type furnace for carburizing. This method ensures even distribution of carbon throughout the part.
