SURFACE HARDENING
Plasma Ferritic Nitrocarburizing
Plasma ferritic nitrocarburizing is a controlled surface hardening process that introduces both nitrogen and carbon into the surface of a component. The process can improve wear performance, fatigue resistance, and surface durability while maintaining the dimensional control required for precision components.
THE PROCESS
How Ferritic Nitrocarburizing Differs from Plasma Nitriding
Ferritic nitrocarburizing is closely related to plasma ion nitriding, but the treatment atmosphere includes carbon-bearing gases in addition to nitrogen and hydrogen. This allows both nitrogen and carbon to diffuse into the surface of the component.
The resulting surface layer can provide an effective combination of hardness, wear resistance, and improved performance under sliding or repeated mechanical contact.
Both elements are introduced into the surface during treatment rather than nitrogen alone.
The treatment is performed at temperatures that keep the base material in the ferritic range.
Process conditions can be developed around the material and required surface characteristics.
JGS can review material, geometry, and performance requirements to determine whether the process is appropriate.
PROCESS OVERVIEW
A Controlled Diffusion Treatment
Plasma ferritic nitrocarburizing modifies the surface of the material rather than applying a conventional coating.
Controlled Atmosphere
Components are processed in a controlled atmosphere containing nitrogen, hydrogen, and carbon-bearing process gases.
Surface Diffusion
Nitrogen and carbon diffuse into the component surface to develop the desired treated layer.
Performance Layer
The resulting surface is engineered around the wear, friction, fatigue, and service requirements of the application.
PERFORMANCE BENEFITS
Why Use Ferritic Nitrocarburizing?
Improved Wear Resistance
Helps protect working surfaces against adhesive wear and repeated mechanical contact.
Improved Scuffing Resistance
The treated surface can provide improved resistance to scuffing and seizure between mating components.
Improved Fatigue Performance
The diffusion zone can enhance surface fatigue performance in components subjected to repeated loading.
Minimal Distortion
Relatively low processing temperatures help preserve component geometry and dimensional accuracy.
Surface Hardness
Creates a hardened working surface while retaining the properties of the underlying component.
Corrosion Resistance
The compound layer can provide additional resistance to corrosion depending on the material and treatment requirements.
APPLICATION FIT
Where the Process Can Be a Good Fit
Ferritic nitrocarburizing can be considered for a range of ferrous components where surface wear, friction, fatigue, or service life are primary concerns.
