Sursulf

CLIN family products such as SURSULF® and TUFFTRIDE® are low toxicity salt bath nitriding processes. The aim of CLIN treatments, via a heterogeneous surface reaction, is to diffuse nitrogen and carbon atoms from the molten salt into the solid metal alloy. This process forms two distinct layers at the surface of treated components:

• A layer of iron nitrides (primarily Ɛ-Epsilon type) and nitrides of alloying elements called the “compound layer”, which also demonstrates a degree of surface porosity.
• A diffusion zone below the compound layer, in which the concentration of nitrides gradually reduces.

The nitrided surface offers benefits such as improved wear, anti-fatigue and anti-seizure properties as well as significantly improved corrosion resistance. For more detailed information on salt bath nitriding, please visit the HEF group page.
