Abstract: The invention relates to an antiwear-coated metal component (1), in particular for a ball valve (6), the tribosurface of which component is at least partially provided with a multi-layer antiwear coating (2). The antiwear coating (2) has at least a metal adhesion layer (3a), an adhesion-promoting layer (3b) and at least one first cover layer (3c). The adhesion-promoting layer (3b) comprises a carbide-forming metal or a boride-forming metal. The at least first cover layer (3c) comprises a hydrogen-free tetrahedral carbon. The invention further relates to a method for applying an antiwear coating (2) to a metal substrate (9) in order to produce an antiwear-coated metal component (1) of this type. The invention further relates to a ball valve, comprising an antiwear-coated metal component (1) of this type and an antiwear coating (2).

Abstract: The invention relates to a substrate holder (1) comprising a first contact (3) for the supply of a potential Us to the substrate (2), a charging region (12) on the surface (11) of the substrate holder (1) being designed such that it can be charged (13) with ions (101, 102) from the ion source (104) of a coating facility (100), and/or a second contact (4) is provided by means of which a freely selectable potential UH different from the potential Us can be applied to an electrode region (14) on the surface (11) of the substrate holder (1).

Abstract: The invention relates to a method for coating a metal component (1) with a hard anti-wear layer (3), which is applied by means of a plasma method at least in a single layer over at least part of the surface of the component (1), wherein droplets (5) deposited on the surface of the applied hard anti-wear layer (3) are mechanically removed, and then a run-in layer (7) that is softer than the anti-wear layer (3) is applied to the surface of the applied and mechanically processed anti-wear layer (3).

Abstract: The present invention is related to a device for influencing the flow in the region of a tube support plate (700, 800) of a tube bundle heat exchanger (100), for the food and beverage industry in particular. A displacement body (10, 11) is provided with a shank part (10c, 11c) which extends in the direction of its axis of symmetry (S) and which, at its end distal to the displacement body (10, 11) is fixedly connected to a connection bend (1000) or connection fitting (1100; 1200) which follows the exchanger flange (500; 1100e) or the connecting piece (800d).
