LDMC-50AQ Bell type Plasma Nitriding Furnace-Post Oxidation nitriding furnace

Post-Oxidation Nitriding Furnace Description:  

This is a thermochemical treatment through which the superficial layer of a steel is enriched of nitrogen and carbon. Such process creates and an enforced layer that increases the hardness of the superficial layer: after the process of surface enrichment we will move onto a controlled and induces oxidation of the artefact, in an oven set under specific temperatures. This process is facilitated by the action of specific gases that generate an oxide veil of a few microns thickness giving it a typical black colouring.

CHARACTERISTICS:

· Increase of superficial hardness;

· Improved resistance to wear and tear;

· Improved resistance to stress;

· Less Friction;

DEPTH :

From 0.05 to 0.30 mm

APPEARANCE:

The product appears neat and in a shade of homogeneous black.

STEELS AFFECTED:

· Nitriding steels;

· Steel used for tools;

· Carbon Steels;

· Tempering Steels;

· Low carbon steels;

· Cast-steels
