Nitriding Vs. Ferritic Nitrocarburizing (FNC)

Nitriding emphasizes diffusion for wear and fatigue improvement. FNC adds carbon to create a thicker white layer with enhanced load capacity, wear, corrosion resistance, and lubricity.

• Nitriding: diffusion-focused, improves wear/fatigue

• FNC: thicker compound layer, carbon enhances properties

• Material suitability and applications differ
