Nitriding in pulse glowing discharge (PLASMA nitriding) is an efficient method to increase hardness and wear-resistance of metals and alloys. Basic technological advantage of the method is the low temperature at which the process takes place resulting in partly volume deformations.
Plasma nitriding is a method with vast technological possibilities. Diffusion layers of desired structure can be obtained, i.e. the diffusion saturation process is controllable and can be optimized in accordance with the particular requirements to the layer qualities.
By regulating the gaseous phase composition and the pulse glowing discharge parameters diffusion layer with monophase-γ'-zone(Fe4N), with monophase-ε-nitride zone(Fe2-3N) or nitrided layers without any nitride zone can be obtained.The achieved nitride zones are dense and solidly connected with the base metal.
IONITECH Ltd. offers 14 standard dimensions of vacuum chambers with 20kW, 25kW, 50kW, 100kW, 200kW pulse power supply. We can make your equipment with one or two working chambers. If you need something really special, our engineers will develop and we will manufacture the plasma nitriding equipment exactly matching your needs.
IONITECH Ltd. manufactures and sells on the world market the biggest range of plasma nitriding and plasma nitrocarburising installations. These installations consist of the following subsystems:
Pulsed Plasma Generator;
Gas Supply System.
Characteristic for plasma nitriding of materials is the active participation of these materials in glow discharge. There are many advantages of this method over classical gas nitriding.
Many parts and tools of all industries are subject to plasma nitriding and nitrocarburising. Different examples demonstrate how plasma nitriding and nitrocarburising solve tough tasks.
