Ion-plasma nitriding

Ion-plasma nitriding

For rings operating in conditions of limited lubrication, developed technology for hardening the surface layer with nitrogen in an environment of low-temperature plasma, which allows to obtain on the surface a hardened layer with hardness up to 650 HRV to a depth of 250...300 microns.

Ion-plasma nitriding (IPN) – modern hardening method for chemical-thermal treatment of products from cast iron, carbon, alloy and tool steels.

This method of hardening the working surface preserves the main advantage of cast iron as a friction material – leaves open the hole of the graphite, which is a natural lubricant and provides a softer work environment.
