A one-piece component includes a first subregion made of a base material, and a second subregion made of the base material as binder with intercalated hard material particles, the second subregion being injection-molded onto the first subregion by means of MIM injection molding, so that an integral connection is formed between the first subregion and the second subregion. Furthermore, a method for producing the one-piece component by means of MIM injection molding is described.
