Abstract
The invention relates to a method for producing a sintered component comprising the steps: providing a metallic powder; filling the powder into a powder press; pressing the powder to form a green compact; removing the green compact from the powder press; sintering the green compact into a sintered component with pores; optional redensification of the sintered component; hardening of the sintered component, wherein the pores of the sintered component, prior to hardening at least in that region of the surface of the sintered component which is subjected to a hardening, are at least partially filled with a filling agent.
Claims7
A method for producing a sintered component comprising the steps:
- providing an iron-based powder consisting of between 0.1 wt. % and 0.9 wt. % of C, between 0 wt. % and 5.0 wt. % of Ni, between 0 wt. % and 2 wt. % of Mo, between 0 wt. % and 1 wt. % of Mn and between 0.1 wt. % and 3 wt. % of copper, the remainder being iron;
- filling the powder into a powder press;
- pressing the powder to form a green compact;
- removing the green compact from the powder press;
- sintering the green compact into a sintered component with pores;
- optionally redensifying the sintered component;
- hardening of the sintered component;
- wherein the pores of the sintered component, prior to hardening at least in a region of a surface of the sintered component which is subjected to hardening, are at least partially filled with a filling agent.
