Abstract:
The invention relates to an apparatus for treating a surface with a at least one gliding arc source comprising at least one gas flow controlling unit (104); and a set of electrodes (102); wherein the at least one gas flow controlling unit (104) and the set of electrodes (102) are controlled to provide a plasma comprising a gas temperature at the set of electrodes (102) above approximately 2000 K. In this way, an optimal or substantially optimal plasma for treating surfaces of samples is achieved.
Abstract:
This invention relates to a plasma surface modification process (and a corresponding a system) of a solid object (100) comprising creating plasma (104) by a plasma source (106), application of the plasma (104) to at least a part of a surface (314) of the solid object (100), generating ultrasonic high intensity and high power acoustic waves (102) by at least one ultrasonic high intensity and high power acoustic wave generator (101 ), wherein the ultrasonic acoustic waves are directed to propagate towards said surface (314) of the object (100) so that a laminar boundary layer (313) of a gas or a mixture of gases (500) flow in contact with said solid object (100) is thinned or destructed for at least a part of said surface (314). In this way, the plasma can more efficiently access and influence the surface of the solid object to be treated by the plasma, which speeds the process time up significantly.
