Plasma Technology

 



An entirely or partly ionized gas that contains electrons, ions, high-energy neutrals, and radicals is referred to as plasma. It frequently goes together with UV photoemission. While gas temperatures can be as low as room temperature, non-thermal plasmas, also known as cold plasmas, can readily be produced at low gas pressures where the electron temperature is around 1 eV (ca. 10,000 K) or higher. So it makes sense to refer to it as a non-equilibrium plasma.

 

A wide range of materials treatments are feasible with plasma technology. Three distinct types of processes on the materials can be activated, depending on the specific physical properties of the plasma created by various ionization systems, in particular: (1) Destroying hazardous or dangerous materials; (2) superficially altering already-existing materials; or (3) developing new materials.

Thermal plasma can be used to create anticorrosion, thermal barriers, anti wear coatings, as well as to eliminate poisonous, halogenated, and dangerous solid, liquid, and gaseous compounds.

Cold plasmas may be used to modify the topography of materials' surfaces as well as produce coatings and surface chemistries that are vastly different from those of the bulk material.

The weight of each of the three lines in relation to an immediate industrial transfer varies. The third one is currently being investigated, whereas the other two are suitable for direct practical use of the techniques. The description of a few industrial procedures will be followed by a cost comparison of a few dangerous material treatments.
