Abstract: A process for plasma treatment of an object's surface to be treated comprising the creation of a plasma, the application of the plasma to the surface to be treated, and the excitation of the surface to be treated, such that it vibrates and undulates. The energy for excitation of the surface may come from the process creating the plasma, from an external source, or from a combination of these two sources. The vibration preferably takes place while the plasma is being applied to the surface to be treated, but depending on the treatment to carry out, it may also take place just prior to and/or just after the application phase.

Abstract: A method of producing powder formed of composite grains comprising a kernel and one or more surface layers. The inventive method comprises the following steps: mixing the grain kernels with a plasmochemical treatment gas; making said kernel/treatment gas mixture flow through a main plasma reactor; and generating a uniform plasma essentially at atmospheric pressure in a treatment region of the main reactor in order to create a plasmochemical reaction between the treatment gas and the surfaces of the kernels so that surface layers form on said surfaces while the mixture flows through the reactor.

Abstract: The invention concerns a device for treating surfaces of containers with plasma comprising a kinematic system for transporting the containers, and a plurality of plasma generators operating at atmospheric pressure, each generator being designed to treat one container at a time, the plasma generator comprising a treatment gas supply system and an electric power supply system including at least one transistor serving as switch, or an LC adapter, designed to supply pulses to the current.
