abstract

Methods of materials deposition and coating based on atmospheric pressure plasma (APP) have gained significant attention these days. Keeping the setup operation at low cost, APP units provide quality pre-processing of chemical agents with subsequent delivery of activated materials onto the surface of interest. These units eliminate the need for vacuum chambers, simplify thermal control of the setup, and widen the range of applicable chemical precursors. Considering the above mentioned factors, the APP becomes a recognizable choice for industrial applications and laboratory use. Demonstrating advanced performance and possibilities, APP reactors are still a subject to certain challenges that have to be overcome with future research. Among them are clogging of output channels with processed material, accurate estimations of mixing zone for efficient material activation, and uniform on-demand distribution of activated material over the substrate. These problems are still waiting for elegant and effective solutions.

We investigate possibilities provided by use of a Linear Plasma Head — a portable APP reactor targeted for enhanced surface coatings. Currently we present our theoretical model of plasma generation in Linear Plasma Head. Numerical simulations are carried out using a parallel computational paradigm. The results and methods discussed in this paper yield with theory-based approach to building an advanced APP-based chemical reactor.
