The conventional Nitrotec® has a pleasing black appearance and vastly superior corrosion resistance to zinc plating. These low temperature, diffusion treatments make low alloy and mild steels up to four times stronger, produce wear resistance equal to hard chromium plating and gives a black finish that has outstanding resistance to corrosion.
An important member of the family of Nitrotec® treatments is NITROTEC-S, a multi stage process, where parts are first machined to a final surface finish required, Nitrotec® treated, surface polished in a controlled manner, followed by a post oxidising treatment. This finish gives a dramatic improvement in frictional characteristics and corrosion resistance properties, superior to those obtained when using hard chromium plating techniques.
