Nitrocarburizing is another case hardening method, which is very similar to nitriding. The material is heated, before being exposed to gas, plasma or salt containing both nitrogen and carbon. This results in a hard surface that is resistant to wear and corrosion.
Nitrocarburizing is a much faster method than nitriding; however, it's important to note that it can only be carried out on ferrous materials such as steel and cast iron. It is a cost-effective process, which makes it a popular choice for improving the hardness of an applicable material in a short span of time.
Examples of parts that are commonly nitrocarburized include gears, dies, shafts and even gun barrels!
