Abstract: A vacuum coating apparatus includes at least a chamber, an arc discharge plasma source, a feeding-reeling unit, and a roller set. The first and second openings are connecting with the feeding or reeling unit so as to allow the substrate to enter and leave the chamber therethrough, respectively. The arc discharge plasma source located inside the chamber generates the plasma, which discharges radially from the arc discharge plasma source as its center. The roller set includes a plurality of the first rollers, which are located in the chamber and enclosing the arc discharge plasma source. A first surface of the substrate is facing the plurality of the first rollers and contacts tightly on the periphery of the first rollers so that the first rollers can rotate by the moving of the substrate. The material evaporated and emitted by the plasma is attached onto the first surface of the substrate.

Abstract: A DC steam plasma torch includes front, middle and rear sections. The front section includes a first amount and a first electrode attached to the first amount, thus defining co-axial first internal and external coolant channels. The middle section includes a second mount and a second electrode co-axially connected to the second mount, thus defining co-axial second internal and external coolant channels. The rear section includes an insulating transient element connected to the second electrode, a window frame connected to the insulating transient element and a window provided in the window frame. A first swirl generator is provided between the first and second sections to receive primary working gas and generating a swirl in the same. A second swirl generator is provided between the middle and rear sections to receive auxiliary working gas and generating a swirl in the same.
