The five methods of carburizing are pack carburizing, gas carburizing, liquid bath carburizing, vacuum carburizing, and plasma carburizing.
1. Pack Carburizing: This method involves placing the metal parts to be carburized inside a container with a sufficient amount of carbon powder. The container is then heated in a furnace at high temperatures for a specific duration of time, typically between 12 to 72 hours. The carbon powder releases carbon which diffuses into the surface layer of the metal, increasing its carbon content and hardness.
2. Gas Carburizing: In gas carburizing, the metal parts are exposed to an atmosphere of carbon-rich gases, such as endothermic or synthetic endothermic gases, along with hydrocarbons like methane, propane, or butane. The parts are heated in a furnace at temperatures ranging from around 1600°F to 1700°F. The carbon in the gases diffuses into the surface of the metal, forming a hardened layer.
3. Liquid Bath Carburizing: This method involves immersing the metal parts into a bath of liquid carburizing agents, such as molten salts or cyanide-based solutions. The bath is heated to high temperatures, allowing the carbon in the liquid to diffuse into the surface of the parts. This process is commonly used for small and intricate parts.
4. Vacuum Carburizing: Vacuum carburizing, also known as low-pressure carburizing (LPC), is a method that takes place in a controlled vacuum environment. The parts are exposed to a precise atmosphere of carbon-rich gases. Vacuum carburizing offers better control and repeatability compared to other methods, and it provides metallurgical and environmental benefits.
5. Plasma Carburizing: Plasma carburizing involves using a plasma discharge to introduce carbon into the surface of the metal parts. The parts are placed in a vacuum chamber, and a plasma is generated by applying a high-frequency electric field. The carbon atoms from a hydrocarbon gas plasma diffuse into the surface of the parts, resulting in carburization.
Each method of carburizing has its advantages and is suited for different applications. The choice of method depends on factors such as the type of metal, desired hardness, part size, and cost considerations.
