Atmospheric pressure high-power impulse plasma source for deposition of metallic coatings
Autor: Ronghua Wei, Kent E. Coulter, Michael A. Miller, Vasiliki Z. Poenitzsch
Publikováno v: Journal of Materials Research. 34:2078-2085
A novel high-power impulse plasma source (HiPIPS) technology that combines atmospheric pressure plasma jets with high-power pulsed direct current generators is described. Pulsed power is applied in microsecond pulses (20 µs) at low duty cycle (10%)

Influence of chemical vapor precursor flow rate on the structure and thermal stability of phase-modulated VSiCN/Ag coatings
Autor: Grant A. Crawford, Forest C. Thompson, Kent E. Coulter, Frank M. Kustas
Publikováno v: Journal of Vacuum Science & Technology A. 39:063409
Ceramic/silver coatings are of interest for tribological and antimicrobial applications. Here, the amorphous phase volume fraction in VSiCN/Ag coatings was varied and the microstructure, mechanical properties, and vacuum annealing behavior of the pha

Dense VSiCN coatings deposited by filament-assisted reactive magnetron sputtering with varying amorphous phase precursor flow rates
Autor: Frank M. Kustas, Grant A. Crawford, Kent E. Coulter, Forest C. Thompson
Publikováno v: Surface and Coatings Technology. 422:127507
Phase-modulated VSiCN coatings were deposited with hot filament assistance by magnetron sputtering of a vanadium target in a gas mixture of argon, nitrogen, and hexamethyldisilazane (HMDS). HMDS flow conditions and total working pressure were varied

Filament-assisted reactive magnetron sputter deposition of VSiN films
Autor: Grant A. Crawford, Forest C. Thompson, Kent E. Coulter, Frank M. Kustas
Publikováno v: Thin Solid Films. 730:138720
Many vapor deposition techniques utilize ion irradiation during growth of transition metal nitride-based films to obtain low porosity and to control nanostructural evolution, phase content, and crystallographic texture. In this study, V1-xSixN films

Investigation of the influence of surface composition on the charge state distribution of ∼keV hydrogen exiting thin carbon foils for space plasma instrumentation
Autor: Kent E. Coulter, Robert Ebert, Vasiliki Z. Poenitzsch, Frederic Allegrini, Georgios Nicolaou
Publikováno v: Advances in Space Research. 57:2420-2426
Energetic neutral atom (ENA) imaging techniques have become a powerful tool for remotely probing plasma environments in space. ENA imagers cover energies from 0.01 keV up to a few MeV, and they use different techniques to cover such a broad energy ra
