Transmission element and method for producing a transmission element

A method for producing a toothed transmission element constructed in the form of a gearwheel, said method comprising:

• forming a partial region with a first material having a first Vickers hardness, the partial region comprising a circular gearwheel core radially inside at least one or more teeth, wherein inner parts of the at least one or more teeth are part of the circular gearwheel core, and the circular gearwheel core and the inner parts of the at least one or more teeth are provided by machining;
• forming an edge region which is formed additively on the partial region, the edge region comprising the at least one or more teeth defining the edge region, with a second material by laser deposition welding, laser wire deposition welding, and/or thermal spraying and/or arc deposition welding and/or a powder bed process and/or selective laser melting, with the second material having a second Vickers hardness which is greater than the Vickers hardness of the first material;
• and
• forming a third material having a third Vickers hardness, the third material located between the first material and the second material, wherein the Vickers hardnesses of the materials decrease stepwise in a radial direction along a section leading from the edge region to the partial region,
• wherein a difference in the Vickers hardness of the second material and the Vickers hardness of the first material is at least 100, and the second material has a Vickers hardness of at least 500, and the first material has a Vickers hardness of at most 400 HV.
