Embodiment Construction

[0023] according to figure 1 , the component assembly of the first exemplary embodiment is composed of a first metal component I, the lower surface of which faces the upper surface of the second metal component II.

[0024] In the area of ​​contact with the surface of the first metal component I, a wear protection layer 1 is applied to the surface of the second metal component II, said wear protection layer being designed as a 3-component layer and containing a carbide-forming metal here A. Metal B and carbon C that do not form carbides. In this exemplary embodiment, the wear protection layer 1 is designed as a molybdenum-aluminum carbide layer applied to the component II via the plasma method.

[0025] A metal adhesion layer 2 is also applied between the wear protection layer 1 and the surface of the metal component II via the plasma method. This metal adhesion layer 2 is used for better attachment of the wear protection layer 1 to the component II.

[0026] Between the me...

Abstract

Disclosed is an antiabrasion-coated metal part (I; II), the tribologically affected surface of which is provided at least in part with an antiabrasive coating (1; 1', 1") that is applied using a plasma process and is in the form of a multicomponent coating comprising at least one carbide-forming metal (A), at least one other metal or semimetal (B) forming no carbides or only non-metallic carbides,and carbon (C).

Description

technical field [0001] The invention relates to a wear-resistant coated metal component according to the preamble of claim 1 , the frictionally loaded surface of which is at least partially provided with a wear-resistant layer applied via a plasma method. Furthermore, the invention also relates to a component assembly according to claim 11 , which at least partially consists of the wear-resistant coated metal component. [0002] The field of application of the invention extends in particular to metallic components whose surfaces are subject to high frictional loads, such as components used in the context of fuel injection systems in motor vehicles, in particular valve seats of fuel injectors, piston guide surfaces of high-pressure pumps, especially the rotation of high-pressure pumps The bearing shell of the bearing part of the shaft. Other mechanical or hydraulic applications, in particular in fuel injection technology, are also conceivable given similar load distributions. ...
