Abstract:
The invention relates to a method for removing at least one inorganic layer from a component, whereby a plasma jet is produced in a working gas containing a reactive gas by means of an atmospheric discharge, the plasma jet is oriented towards the inorganic layer, the inorganic layer is at least partially melted by means of the plasma jet, and the at least partially melted inorganic layer is removed from the surface by the gas flow of the plasma jet. The inventive method can be used especially for delayering adhesive surfaces of two components, and for machining headlight components. The invention also relates to a device for producing a plasma jet for carrying out the inventive method.
Abstract:
The invention relates to a method for producing a low-pressure plasma consisting in generating a negative pressure in a low-pressure chamber by means of a vacuum pump and in leading a plasma beam at a high pressure to said low- pressure chamber. Said invention also relates to different use a low-pressure plasma for treating surfaces, surface coatings or gases. A device for producing a low-pressure plasma is also disclosed.
Abstract:
A mechanism for plasma surface treatment includes a rotating head having at least one eccentrically disposed plasma nozzle for generating a plasma jet directed in parallel with the axis of rotation. The nozzle includes a swirl system for swirling the plasma jet.
Abstract:
A plasma nozzle for treating surfaces, especially for the pre-treatment of plastic surfaces, with a tubular, electrically conductive housing (10), which forms a nozzle channel (12), through which the working gas is flowing, an electrode (18), disposed coaxially in the nozzle channel, and a high-frequency generator (20) for applying a voltage between the electrode (18) and the housing, the outlet of the nozzle channel (12) is constructed as a narrow slot (32), which extends transversely to the longitudinal axis of the nozzle channel.
