Industries in which Plasma Nitriding is Implemented
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.
Here are some examples of industries where plasma nitriding and nitrocarburising are applied:
• Automobile Industry - crankshafts, camshafts, gears, pistons, cylinders, valves, valve springs, synchromesh rings;
• Metal Casting and Moulding Industries - moulds for non-ferrous metals and alloys;
• Aluminium Industry - dies for casting and extruding;
• Plastics Industry - extruder screws, cylinders, moulds for injection moulding;
• Machine Building - shafts, spindles, slide-rails, instruments for cold and hot rolling, dies and punches for deep drawing, pump cylinders, milling and drilling tools (milling cutters, rams, drills, taps, broaches, etc.);
• Powder Metallurgy - gears, bushes, synchromesh rings;
• Power Engineering - turbines, shafts, spindles, gears.
Results after Plasma Nitriding
These are some of the possible steel grades for Plasma Nitriding and Nitrocarburising. For information about other steel grades and results, please, do not hesitate to contact us at:
Microhardness in Depth of nitrided steels
The depth of the diffusion of nitrogen in the steel depends on the Plasma Nitriding Process parameters.
Metallographic images of Compound (White) Layer and diffusion zone
The thickness of the compound (white) layer and the depth of the diffusion zone could be controled by the Plasma Nitriding Process parameters.
Phase structure of Compound Layer
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.
