Abstract:
Procedimiento para el recubrimiento de superficies - en el cual se genera un rayo de plasma (28; 28¿; 28¿) por el paso de un gas de trabajo a través de una zona de activación (12), - en el cual se alimenta un material precursor de modo separado del gas de trabajo dentro del rayo de plasma, - en el cual se hace reaccionar el material precursor con la ayuda del rayo de plasma y - en el cual se deposita el producto de reacción sobre la superficie (34), - donde tanto la reacción como también la deposición tienen lugar bajo una presión atmosférica caracterizado por el hecho de que por la colocación de una tensión alterna de alta frecuencia se genera una descarga de arco en los electrodos (10, 18) colocados dentro de la zona de activación.
Abstract:
A method for coating surfaces, for which a precursor material is caused to react with the help of plasma and the reaction product is deposited on a surface, the reaction as well as the deposition taking place at atmospheric pressure, such that a plasma jet is generated by passing a working gas through an excitation zone and the precursor material is supplied with a lance separately from the working gas to the plasma jet.

Abstract:
The invention relates to a component for a painting installation, for example a grid, a suspension, a cover and the like, that is splashed with paint during the operation of the painting installation. The invention is characterised in that the component is coated with a plasma polymer coating containing oxygen, carbon and silicon.
Abstract:
The invention relates to a method for increasing the surface tension of a substrate consisting of a thermoplastic polymer, whereby the surface of the substrate is fully or partially exposed to a plasma such that the surface tension is increased, and the plasma-treated surface is then brought into contact with a liquid medium in order to stabilise the increased surface tension.

Abstract:
The invention relates to an article that comprises a substrate, and a plasmapolymer coating applied across the surface of the substrate and comprising silicon, oxygen and carbon. An analysis by ESCA gives an amount of substance ratio for O:Si greater than 1.25 and less than 2.6, and the amount of substance ratio for C:Si is greater than 0.6 and less than 2.2. According to a preferred embodiment, the coating contains, based on its total atom content without hydrogen and/or fluorine, a minimum of 22 and a maximum of 27 atomic percent of Si, a minimum of 25 and a maximum of 50 atomic percent of O, and a minimum of 25 and a maximum of 50 atomic percent of C.
