Abstract: The invention relates to a finishing method for a workpiece with a finishing layer, having the following steps: a. providing a workpiece with a treatment surface; and b. providing the treatment surface with a finishing layer. The finishing method is primarily characterized in that the method has at least the following step: c. reducing stresses in the finishing layer. The invention additionally relates to a workpiece with a finishing layer, wherein the finishing layer is re-compressed and/or the stress in the finishing layer is neutral or a compressive stress. By virtue of the aforementioned finishing method and the workpiece, a high quality and a long service life of the finishing layer can be achieved using inexpensive means.

Abstract: The invention relates to an apparatus for coating a workpiece, having at least the following components: a laser device for generating a laser beam with a laser focus; a powder nozzle; and an advancing actuator system for advancing the laser device and the powder nozzle, wherein the laser device is designed for thermally treating powder material supplied by the powder nozzle for coating a surface of a workpiece and/or for thermally treating this surface. The apparatus also has: —a measuring device for recording coordinates of a point on a surface to be coated; and at least one adjusting device for adjusting the laser focus and the powder nozzle relative to one another. With the workpiece proposed here and the associated reference mark, high-precision application of a finishing layer to the workpiece can be carried out.

Abstract: The invention relates to a coating for coating a base body comprising iron; and from 10% to 25% by weight of chromium; and from 0.3% to 5% by weight of carbon; and from 0.5% to 15% by weight of vanadium.

Abstract: The invention relates to a workpiece to be coated with a finishing layer. The workpiece has a support body with a treatment surface, wherein the finishing layer is applied or can be applied onto the treatment surface. The workpiece is primarily characterized in that the workpiece is provided with a reference mark to which a stationary coordinate system that is highly precise relative to the workpiece can be repeatedly assigned. By virtue of the aforementioned workpiece and the corresponding reference mark, a finishing layer can be applied onto the workpiece in a highly precise manner, and the finishing layer can be reprocessed.

Abstract: The invention relates to a device (1) for laser cladding, a method (100) for operating such a device, and a component (4?) produced using such a method and/or such a device comprising a laser cladding unit (2) having at least one laser cladding head (3) disposed thereon, one or more material sources (5) for supplying the laser cladding head with a material (M) to be applied, and a laser beam source (6) for supplying the laser cladding head with laser light (L) for carrying out the laser cladding, wherein the device is configured to apply material layers (42, 43, 44) from an adjacent application cladding track (MS) to a surface (41) of a component (4) in the form of at least a first layer (42) made from a material (M) that comprises structures (42s) projecting from the surface of the first layer and having a first hardness (H1), and a second layer (43) applied thereto made from a material (M) having a second hardness (H2) that is less than the first hardness, and the application process is controlled so that t

Abstract: The invention relates to an apparatus for laser-deposition welding with multiple laser-deposition welding heads and to a method for operating such an apparatus comprising a laser-deposition welding unit with multiple laser-welding heads arranged thereon for the (quasi-) simultaneous depositing of material (M) onto a surface of a component and also comprising one or more conveying units for supplying the laser-deposition welding heads with the material (M) to be applied and further comprising one or more laser-radiation sources for supplying the laser-deposition welding heads with laser radiation (L) for carrying out the laser-deposition welding.
