The method includes providing a substrate and distributing particulate material from the feed mechanism onto the substrate. The particulate material includes agglomerated particles with diameters between 30 and 100 microns. The method also includes activating the energy source to produce a beam spot on the particulate material, the substrate, or both and at least partially melting the particulate material, the substrate, or both with the beam spot to form a bonded layer of particulate material on the substrate.

A method for simply producing components suitable for use under high loads and risks of wear and which have a core portion which consists of a metal material and a wear-resistant layer on a peripheral surface of the core portion is disclosed. A core portion blank is provided and consists of the metal material whose dimension in a first spatial direction is greater than the desired finished dimension of the core and whose second dimension is smaller than the desired finished dimension is provided. A material that forms a wear-resistant layer in the component is applied to a peripheral surface of the core portion blank. The composite body is shaped to form the component. The component may then be optionally finished.
