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.
