Abstract

A method for the powder metallurgical production of a component may include providing a mould, filling a first metallurgical powder into the mould such that an outer contact surface of the first metallurgical powder in the mould forms an angle of 55° to 65° with an axis of a future green product, and filling a second metallurgical powder that is distinct from the first metallurgical powder into the mould such that the second metallurgical powder adjoins the outer contact surface of the first metallurgical powder. The method may also include producing the green product out of the first metallurgical powder and the second metallurgical powder, and sintering the green product to produce the component.
