Gas Nitriding is a heat treatment process which diffuses nitrogen into the surface of a metal to create a case-hardened surface.
Ammonia is injected into the furnace provoking a catalytic reaction. The nascent nitrogen diffuses into the matrix to form metal nitrides.
In a vacuum purged furnace, pressure, temperature and process gas composition can be controlled at any stage of the process to achieve expected nitrides and diffusion depth.
Controlling the nitriding process is achieved by controlling the nitriding potential Kn :
Gas Nitriding is an efficient process for automotive, aeronautics, watchmaking and tooling industries that need to improve properties of parts like
If your process doesn’t involve working with bulk or very complex parts, you should consider plasma nitriding.
If your need to nitride sintered parts or to perform partial nitriding of your parts, plasma nitriding is the only solution.
