The Arc Plasma Torches

2016
This chapter focuses on the theoretical description of the physical processes in the Arc plasma torches with different technological applications. The features of electric Arcs and their models for the study of Arc plasma torches are presented. The need to determine the two-dimensional electromagnetic field, especially in the case of an open free Arc ...

Electrode erosion in plasma torches

Plasma Chemistry and Plasma Processing, 1992
Cathode 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 ...

Diagnostics of a DC plasma torch

SPIE Proceedings, 1991
Optical 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.

Arc plasma jets of a nontransferred plasma torch

IEEE Transactions on Plasma Science, 1996
The plasma flow of a nontransferred plasma torch used for thermal plasma processings is produced by the arc-gas interactions between a cathode tip and an anode nozzle and expands as a jet through the nozzle. In this work, numerically calculated images of the are plasma characteristics are found over the entire plasma region, including both an arc-gas ...

Electrode Phenomena in Plasma Torches

Annals of the New York Academy of Sciences, 1999
ABSTRACT: The performance of most plasma generators using electric arcs is determined by the design of the electrodes. While the cathode design is the dominant factor in determining the limitations in torch operating current and power level as well as life between maintenance, the anode design dominates the functional performance for most torches, i.e.

Induction-Coupled Plasma Torch

Journal of Applied Physics, 1961
A new method of generating a stable plasma at atmospheric pressure using inductive coupling at a frequency of several Mc is described. Methods of starting and operating this plasma in argon, and mixtures of argon with helium, hydrogen, oxygen, and air are discussed.
