What is Diffox
When good sliding wear resistance in conjunction with excellent corrosion resistance is required, Diffox is the answer. Diffox forms a complex case of diffusion nitrides and oxides on low and medium alloy steels that offer a superior mix of properties. It is a surface conversion rather than a coating and therefore it is integral with the material surface. Conventional nitriding does not allow the diffusion depth and white layer to be optimized, however our Diffox coating does excatly that to provide you the optimal surface for the specific application, plus the added benefit of surface.oxide for enhanced corrosion and wear resistance.
- Diffox treatments can be applied to parts directly after machining
- High resistance to seizing and scuffing
- High resistance to corrosion
- High resistance to fatigue
- High resistance to wear
- Insignificant distortion or size change
- Good retention of lubrication
Properties of Diffox
Due to Diffox being a modification of the steel surface, properties such as wear resistance and corrosion resistance of Diffox change with different base materials.
The ceramic top layer is generally between 10 to 20 microns in thickness with hardness’s of between 800 and 1500Hv. Furthermore, due to special pre-, intermediate and post finishing procedures the smoothness of the layer shows added sliding wear resistance. Depending on material and processing conditions, corrosion resistance in excess of 400 hours salt spray have been recorded.
What can it be applied to
Diffox is suitable for a wide variety of carbon steels, low alloy steels and even cast irons. Because it is a relatively low-temperature process, part distortion is reduced provided the initial heat treatment has been done correctly. Contact us for information on this.

Why use Diffox?
The Diffox process significantly enhances the corrosion protection of steel components and thus provides a more effective and environmentally acceptable alternative to deposition coatings, e.g. chrome and nickel plating. Furthermore, this process used in conjunction with carbon steels has proven itself as a viable replacement for stainless steels with an appreciable reduction in material and manufacturing costs.
