Tufftride® and its synonymous trade-names Tenifer®, Melonite® is a relatively simple CLIN process to operate and maintain and delivers exceptionally uniform case hardening.

The Tufftride® process includes oxidization after nitriding.

This environmentally friendly surface treatment offers many advantages on ferrous material such as: Wear Resistance, Seizure Resistance, Stable & low friction properties, Mechanical damage resistance, Corrosion Protection, Heat Stability with a uniform black appearance.

Treatment Parameters

Treating ferrous materials (steel, cast iron, stainless steel and Inconel alloys) at temperatures typically between 540°C and 580°C and treatment times between 30 and 210 minutes.


TSUK is home to the largest nitrocarburising baths in the UK, we can treat parts up to 1 metre in diameter and 3.2 metres in length.
