Abstract

At least one coated valve seat region has at least one first layer and a second layer, the second layer is arranged on the first layer, and the first layer and the second layer are different. The first layer and the second layer are each formed by a local thermal deposition welding method. In the case of a cylinder head of an internal combustion engine, a valve seat region is formed by depositing a first layer on a substrate material of the valve seat by a laser deposition welding method in one method step and, in a subsequent method step, depositing a second layer on the first layer by a laser deposition welding method. The second layer contains a material which exerts a material hardening effect.
