Got a frictional wear or corrosion prevention application?
Ferritic nitrocarburizing, or FNC for short, is a thermochemical process where nitrogen (via ammonia) and carbon react with the iron content at the surface of alloy and carbon steels to create a shallow (microns), very high hardness “compound” layer. The part is heated to a general temperature range between 1000 – 1075°F in a nitrogen and carbon enriched atmosphere to form a hard “shell” on the surface of the part, and a very shallow diffusion zone beneath this layer.
Additionally, an oxide layer can be added at the surface of FNC parts which will further inhibit corrosion. The oxide layer appears as a dark gray matte finish on the parts that turns black when oiled. This process can stand up to rigorous salt spray requirements and can be an effective replacement for environmentally unfriendly chrome plating.
