CLIN™:
Trade name ARCOR® SURSULF® TENIFER® TUFFTRIDE® MELONITE® NUTRIDE® QPQ®
The various liquid ionic nitriding treatments of the HEF group are grouped under the name CLIN™ meaning "Controlled Liquid Ionic
Nitrocarburizing".
CLIN™ technologies are mainly applied to ferrous alloys (from low-carbon steel to high-alloy steels and cast irons), and are carried out
between 500°C and 630°C for periods of 30 to 240 minutes.
Unlike electrolytic coatings, there is no risk of hydrogen embrittlement with CLIN™ technologies.
Examples of use:
CLIN™ technologies, liquid ionic nitriding with low environmental impact, play a key role in meeting the changing requirements in modes of
transportation. They are, for instance, at the heart of vehicle electrification and particle emission limitations because they significantly improve
the performance of braking and transmission systems. The combined benefits offered by this surface treatment make CLIN™ technologies a
robust, high-performance and competitive solution. In accordance with REACH regulations, CLIN™ technologies are positioned as the ideal
replacement for harmful procedures like hard chrome plating.
For example, they can be used to combine wear resistance, corrosion resistance, fatigue resistance, and resistance to chipping on parts as
varied as:
• Differentials (axles, casings, washers, gears, etc.)
• Braking systems (discs, pistons, pad holders, etc.) and shock absorbers
• Cylinders (rods, pistons, etc.)
• Valves
• Articulated shafts and windshield wipers
• Axle joints
• Crane joints
• Electrical equipment mechanisms
• Gears and camshafts
• Moulds for
