Eco Friendly Plasma Nitriding Process

Conventional nitriding is potentially very hazardous to environment due to use of poisonous chemicals like cyanides and ammonia whereas plasma nitriding process uses non toxic & precisely controlled gas mixtures. Plasma nitriding process is hence recommended as an alternative, environmentally benign surface treatment process. A plasma nitriding system developed by FCIPT, a division of IPR with support of DST & GUJCOST is installed at IGTR Ahmedabad. The Facility is available for use of industries at Indo German Tool Room, Vatva, Ahmedabad.


Vacuum Chamber Size : 1 meter Dia x 1 meter Height
Loading Capacity : 500 Kgs.(Subjected to size & Shape of jobs)
Operations : Fully Automatic PLC/PC based Control with SCADA Packages
Power Supply : Pulsed DC 1000 V
(plasma Reactor Frequency 2-30 KHZ)
Gases Used For Plasma : Nitrogen, Hydrogen, Argon


An autonomous body under ministry of MSME Govt of India provides technological help to MSME in tools Die making and training. Now the Plasma nitriding services are also available at IGTR.

Application of Plasma Nitriding Process

  1. Automobile Industry - crankshafts, gears, piston, cylinders, valves, valve springs, synchromesh rings.
  2. Metal Casting & Moulding industries - moulds for non ferous metals and alloys
  3. Forging Industry - all kinds of dies for hammering and pressing (cold forging, impression forging, open die forging)
  4. Aluminum Industry- dies for casting and extruding
  5. Plastic Industry - Extruder screws, cylinders, moulds for injection moulding
  6. Machine Building - Shafts, spindles, slide- rails, instruments for cold & hot rolling dies and punches for deep
  7. drawing, pump cylinders, milling and drilling tools (milling cutters, rams, drills, taps ,broaches, etc)
  8. Powder Metallurgy – gears ,brushes, synchromesh ring
  9. Power Engineering - turbines, shafts, spindles, gears
