Prediction of radiative heat transfer in argon arc plasmas using the method of partial characteristics
Aubrecht, Vladimír
Radiative heat transfer is a significant energy exchange process in arc plasmas. In the paper, an approximate Method of partial characteristics (MPC) is used to evaluate radiation intensities in argon arc plasmas of cylindrical symmetries at the atmospheric plasma pressure.
Diagnostics of Breakdown in Electric Arc Exposed to External Magnetic Field
Hlína, Jan ; Šonský, Jiří
An arc in external magnetic field acquires a helical shape and when the magnetic field exceeds a critical value the arc starts to oscillate. The oscillations may lead to many types of shortenings (breakdowns) between the adjacent windings of the arc path. We have investigated experimentally the steepness of the voltage fall reflecting the breakdown and the influence of mean arc voltage and electrode polarity on this characteristic.
Study of influence of discharge parameters on mechanical properties of plasma treated surfaces
Buršíková, V. ; Zajíčková, L. ; Buršík, Jiří ; Janča, J.
Several different types of intermediate layers between the polycarbonate substrate and the plasma deposited hard SiOx-like protective coating have been studied. By the help of an optimized fracture resistant intermediate multilayer system and hard SiOx-like protective coating the original PC surface hardness was increased by almost two orders of magnitude.
