Abstract (en)

[origin: WO2019161981A1] 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).
