Investigative Studies of Plasma Torch Hazards
American Industrial Hygiene Association Journal, 1968Abstract Potential health hazards from a medium output plasma torch used in a biological laboratory were investigated, and some industrial applications of higher output plasma torches were surveyed. Exposures to intense ultraviolet radiation, noise, and noxious gases and fumes were measured.

Design and characteristics of a new type laminar plasma torch for materials processing
Plasma Science and Technology, 2019Laminar Plasma Jet (LPJ) generated by Laminar Plasma Torch (LPT) has a favorable temperature and velocity distribution. Thus, it is superior to the turbulent plasma jet in material processing.

Numerical Study of Plasma–Electrode Interaction During Arc Discharge in a DC Plasma Torch
IEEE Transactions on Plasma Science, 2018Energy transfer within an arc is of crucial importance in numerous applications, such as thermal spraying and electric propulsion (arcjet and magnetoplasmadynamic thruster).

Electrode erosion in plasma torches
Plasma Chemistry and Plasma Processing, 1992Cathode erosion rates are reported (or copper electrodes in a simulated plasma torch operating at atmospheric pressure. The are current was 100A (or most experiments; the magnetic field used to move the arc varied between 0.001 and 0.15 T. Different plasma gases were used (Ar, He, air, N2, CO, and mixtures of the noble gases with O2, N2, CO, CH4, Cl2 ...

Production of active species in an argon microwave plasma torch
Journal of Physics D: Applied Physics, 2018In this paper, results from the computational investigation of active species production in an argon microwave plasma torch are presented. We address the main paths of species creation and quenching and focus on their spatial distributions.

The plasma torch is a poorly understood, little known prodigy among the physical modalities used in medicine. It is unknown to most physicians because it is presently an experimental tool, references in the medical literature are sparse, and it masquerades under several aliases.

Plasma Torch Diamond Deposition
2002Deposition of diamond films using a thermal plasma has some process characteristics that are fundamentally different from those of all the other deposition methods. The thermal plasma generated either by an electric arc or by a radio frequency induction discharge (rfi), has extremely high energy densities (up to 108 J/m3) and temperatures (typically

Diagnostics of a DC plasma torch
SPIE Proceedings, 1991Optical emission spectroscopy, Langmuir probes, and calorimetric techniques have been used to characterize the plasma jet in a DC plasma torch diamond deposition apparatus. The experimental data are compared to calculations based on a thermodynamic equilibrium model.
