(L&PTD)

Plasma - regarded as the fourth state of matter results when atoms and molecules of matter in a highly energized gaseous state dissociates into free positive and negative charged species and gets transformed into a conducting gas like fluid with the free charges governing its behavior and properties.

Fire is an example of a plasma, so is the gas inside a tubelight when it is switched on.

The L&PTD activities related to R&D studies on Plasma includes: Study of the basic physical processes involved in Plasma state of matter Development of plasma based devices and their applications.

Key Research Areas  Development of high power plasma torches for processing of reactive metals and alloys. Qualification, testing and diagnostics on constrictor arc plasma jet devices. Development of Plasma Torch Aerosol generator for Nuclear Aerosol Test Facility. Development of Wire Arc Plasma Spray Torch  Computational modeling of temperature and flow fields in transferred and non-transferred arc jets impinging on a substrate Study of arc root movement in hollow electrode plasma torches and chaotic behavior of arc plasma Development and evaluation of Plasma sprayed ceramic-metal duplex coatings for nuclear applications Reactive plasma spray synthesis of nanocrystalline aluminum oxide Application of thermal plasma in biomedical waste incineration, surface engineering, decommissioning of contaminated metal structure, melting of refractory metals, nano-particle deposition etc. Development of Microwave plasma processed Diamond like Carbon super hard Coatings
