This video explores the differences between low-pressure and high-pressure plasmas, explaining how operating conditions influence plasma behavior and properties. It highlights the distinct technological applications of each type, from surface treatment and thin-film deposition to large-scale industrial processes. Viewers are introduced to the advantages and limitations of both regimes, showing why certain applications favor one type of plasma over the other. The video also emphasizes how tailoring pressure conditions enables plasma technologies to meet specific industrial and scientific needs.
