Comparing Nitride Layers to Coatings.
While there are many surface coatings available to protect parts from wear and corrosion, they are more susceptible to pitting, flaking and peeling from the surface. When this happens, the part either needs to be scrapped, or the surface needs to be stripped and re-coated; in some circumstances, this requires the disposal of hazardous chemicals. This is not only time consuming, but can be very costly for the manufacturer.
Nitriding (plasma/ion or gas) and Ferritic Nitrocarburizig (FNC), on the other hand, create what is called a “compound zone” (aka white layer) that is not susceptible to peeling, flaking and chipping. To learn more about this subject, click here.
