摘要:
The invention concerns the production of anti-wear layers disposed on surfaces of internal combustion engine components which are exposed to frictional wear. According to the method, anti-wear layers are formed on the particular surface by means of electrical arc discharge under vacuum conditions. The anti-wear layers are formed from at least approximately hydrogen-free, tetrahedral amorphous (ta-C) carbon consisting of a mixture of sp 2 and sp 3 hybridized carbon, and have a microhardness of at least 3500 HV and an arithmetic mean surface measure R a of 0.1 μm, without mechanical, physical and/or chemical surface treatment.

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.

The invention relates to an arrangement for producing coatings on substrates in vacuo. A plasma is produced by electric arc discharge on a target that is connected as the cathode and the arc discharge between an anode and the target is ignited by means of a mobile focused laser beam that is directed through a window onto the surface of the target. The aim of the invention is to provide a technical solution that allows an undesired coating in the window zone of a vacuum chamber to be considerably reduced. To achieve this aim, a permanent magnet or electromagnet is arranged between the window and at least one target laterally next to, above or below the optical axis of the laser beam and the laser beam is guided through a magnetic filed produced by the permanent magnet or electromagnet.

A microwave plasma process device (10) is provided with a plasma ignition enhancing means for enhancing plasma ignition by microwaves. The plasma ignition enhancing means comprises a deuterium lamp (30) which generates vacuum ultraviolet rays, and a penetration window (32) guiding the vacuum ultraviolet rays, which have penetrated the same, to a plasma excitation space (26). The penetration window (32) is constructed as a convex lens, focusing the vacuum ultraviolet rays to enhance the ionization of the plasma excitation gas. Such arrangement makes it possible to effect plasma ignition easily and rapidly.

The invention relates to a plasma apparatus where plasma is generated utilizing microwave discharge and laser excitation is performed and plasma processing is performed. More specifically, in a plasma apparatus where microwave from a microwave oscillator (1) is transmitted through a microwave transmission path (2) to a microwave circuit (6), and plasma is generated by microwave discharge within the microwave circuit, a plasma generating medium for generating the plasma is filled in a space formed between the conductor wall to constitute a part of the microwave circuit and dielectrics installed opposite to the conductor wall, and the microwave circuit forms microwave mode having the electric field component orthogonal to the boundary between the dielectrics and the plasma.
