Abstract
A coated component, in particular to a rolling bearing part, made from a metallic substrate (2), and a PVD coating (3), which is applied to the substrate (2), formed of chromium and having a thickness of less than 2 μm, wherein the PVD coating (3) forms the surface of the component, and a compound of chromium and at least one further element is formed on the component surface.
Claims13
A coated component, comprising
- a metallic substrate,
- a PVD coating made from chromium and deposited on the substrate with a thickness of less than 500 nm and greater than 100 nm,
- wherein the PVD coating forms a surface of the component and a barrier made from a compound of chromium and at least one additional element is formed on said component surface, and the at least one additional element is oxygen or nitrogen or both,
- wherein the component is a rolling bearing part.

A process for producing a coated component comprising the following steps:
- providing a rolling bearing component formed of a metallic substrate,
- depositing a PVD coating as a chromium layer with a thickness of less than 500 nm and greater than 100 nm on the substrate in a PVD process while forming a component surface, and
- forming a barrier made form a chromium compound of the chromium layer and at least one additional element on the component surface, with the at least one additional element comprising oxygen or nitrogen or both.
A rolling bearing, comprising
- a coated component including:
- a metallic substrate,
- a PVD coating made from chromium and deposited on the substrate with a thickness of less than 500 nm and greater than 100 nm,
- wherein the PVD coating forms a surface of the component and a barrier made from a compound of chromium and at least one additional element is formed on said component surface, wherein the at least one additional element is oxygen or nitrogen or both, and
- a combined thickness of the PVD coating and the barrier is less than 500 nm and greater than 100 nm.
