The invention relates to a device for generating a hollow cathode arc discharge plasma, consisting of two plasma sources (11; 12), each comprising a hollow cathode (13; 14) and an electrode (15; 16) that is associated with the hollow cathode (13; 14) and has an opening extending through the electrode (15; 16), wherein the hollow cathodes (13; 14) of the two plasma sources (11; 12) are connected to a pulse generator (17) that generates a bipolar, medium frequency pulsed voltage between the two hollow cathodes (13; 14). In both plasma sources (11; 12), the hollow cathode (13; 14) is connected in an electrically conductive manner to the associated electrode (15; 16), either directly or with the intercalation of at least one component (38; 39) that delimits the current direction.

According to the invention, in plasma-activated high-rate evaporation of an oxide former, monomers are applied in addition to oxygen in such a way that the evaporated oxide formers and the oxygen and the monomers have a preferential direction on the substrate and pass through a high-density plasma zone. More than 50 wt % of the coating on the substrate consists of inorganic molecules and under 50 wt % of partially cross-linked organic molecules. The process is used for packaging, window glazing, mirrors, decorative surfaces or façade linings.

The process and appropriate device is designed to facilitate the coating at a high rate of large-area electrically conductive and electrically insulating substrates with electrically insulating and electrically conductive coatings comparatively economically. The substrates are primarily strip-like and are especially plastic foils more than a metre wide. According to the invention, negative and positive voltage pulses are alternately applied in a prior art vacuum coating device to the electrically conductive substrate or, in the case of electrically insulating substrates, to an electrode arranged behind it, e.g. the cooling roller, relative to the plasma or to an electrode at approximately plasma potential. The shape, voltage and duration of the pulses is suitable for the coating purpose and the material. The process is particularly suitable for applying wear and corrosion protection and barrier coatings for use, for example, in the packaging industry.

The invention relates to a process and device for depositing SiOx coatings on a substrate by the evaporation of SiO2 using an electron beam linear evaporator with a magnetic trap by guiding the electron beam along a deflection line parallel to the longitudinal axis of the magnetic trap to the material to be evaporated and deflecting it discretely along the deflection line in such a way that a series of evaporation points (5) with a high power density is formed, whereby the magnetic field between the material to be evaporated and the substrate to be coated reaches 50 to 100 G and the product of the distance and the average magnetic flux density between the material to be evaporated and the substrate is at least 15 G x m.
摘要:
A plasma generation process that is more optimized for vapor deposition processes in general, and particularly for directed vapor deposition processing. The features of such an approach enables a robust and reliable coaxial plasma capability in which the plasma jet is coaxial with the vapor plume, rather than the orthogonal configuration creating the previous disadvantages. In this way, the previous deformation of the vapor gas jet by the work gas stream of the hollow cathode pipe can be avoided and the carrier gas consumption needed for shaping the vapor plume can be significantly decreased.
