Nitriding / Nitrocarburising furnaces

Currently, you can choose between different methods of forming the desired layers - nitriding under vacuum, nitriding in gas (controlled atmosphere), plasma (ionic) nitriding.

The vacuum nitriding processes take place at temperatures of 400-600 ° C and the gaseous atmosphere is composed of NH3, N2, N2O eventually CO2. The advantages of this heat treatment process include the choice of layer composition, faster process kinetics, compact compound layer, low gas consumption, surface cleanliness of processed parts, ecology.

Using the method of process control using the nitriding number, quality and reproducible results of this chemical-heat treatment can be obtained.
