Abstract
A method for producing a coated object, wherein the method comprises the steps of: A substrate is provided in a reaction chamber and an anti-wear layer is deposited on a surface of the substrate by physical vapor deposition, wherein a target is provided in the reaction chamber, which target contains at least a first transition metal Ma that is a transition metal from the fifth or sixth group of the periodic table, in order to produce an Ma2C phase in the anti-wear layer, and wherein the proportion of Ma of the Ma2C phase in the anti-wear layer is at least 60 atomic percent, based on the total quantity of transition metals in the anti-wear layer. Furthermore, a coated object is indicated.

A method for producing a coated object, wherein the method comprises the steps of:
- providing a substrate in a reaction chamber, and
- depositing an anti-wear layer on a surface of the substrate by means of physical vapor deposition, wherein a target is provided in the reaction chamber, which target contains at least a first transition metal Ma, which is a transition metal from the fifth or sixth group of the periodic table, to produce a Ma2C phase in the anti-wear layer, and wherein the proportion of Ma of the Ma2C phase in the anti-wear layer is at least 60 atomic percent, relative to the total quantity of transition metals in the anti-wear layer.
A coated object comprising a substrate and an anti-wear coating disposed on a surface of the substrate, wherein the anti-wear coating comprises a Ma2C phase, wherein Ma is a transition metal of the fifth or sixth group of the periodic table, and wherein the proportion of Ma in the anti-wear layer is at least 50 atomic percent, based on the total quantity of transition metals in the anti-wear layer.
