Advantages of Ion Nitriding

•  Furnace parameters can be tailored to inhibit or enhance both the development of white layer growth and diffusion depth.

•  Lower operating temperatures allow nitriding below tempering temperatures resulting in less distortion and no adverse effects on core properties.

•  Sputtering steps can remove chromium oxide layers present in higher alloyed material, such as stainless, allowing trouble free nitriding.

•  Fully reproducible layer structures can be achieved.

•  Surfaces requiring protection from nitriding can be masked using mechanical means (sheet masks). This negates the application and removal of stop off paints or plating.

•  Minimal or no increase in the surface roughness of the part.

• Improvements in wear and corrosion resistance.

• Increase in fatigue strength.

• Reduced co-efficient of friction.

• Varying pressure dictates the degree of contour following. For example, a blind hole can be nitrided or literally skipped over.

• Wider range of nitridable materials.

• Able to meet the higher demands of industry for specification tolerances and documentation.

• No delamination concerns with white layer since it is an integral part of the substrate.

• No significant dimensional changes.
