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;

       •   Forging Industry - all kinds of dies for hammering and pressing (cold forging, impression forging, open die forging);
       •   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.

Microhardness in Depth of nitrided steels

The depth of the diffusion of nitrogen in the steel depends on the Plasma Nitriding Process parameters.
  • Microhardness in depth of steel H13 after plasma nitriding
  • Microhardness in depth of steel CA6NM after plasma nitriding
  • Microhardness in depth of steel 20NiCrMo2-2 after plasma nitriding
  • Microhardness in depth of steel 38CrAlMo7 after plasma nitriding
  • Microhardness in depth of steel 42CrMo4 after plasma nitriding
  • Microhardness in depth of steel X100CrMoV5 after plasma nitriding
  • Microhardness in depth of steel 17-4 PH after plasma nitriding
  • Microhardness in depth of steel 16MnCrS5 after plasma nitriding
  • Microhardness in depth of steel SS 304 after plasma nitriding

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.
  • White Layer and Diffusion Zone of steel 31CrMoV9 after Plasma Nitriding
  • White Layer and Diffusion Zone of steel 42CrMo4 after Plasma Nitriding
  • White Layer and Diffusion Zone of steel AISI 1045 after Plasma Nitrocarburising
  • White Layer and Diffusion Zone of steel SS 304 after Plasma Nitriding
  • White Layer and Diffusion Zone of steel 16MnCr5 after Plasma Nitriding
  • White Layer and Diffusion Zone of steel AISI 4140 after Plasma Nitriding

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.
