The invention relates to a method for producing a net- shape vane for a rotary vane pump , which vane is preferably open -pored and consists of a metal sinter material. The vane has at least one first front face and one second front face which is preferably oriented parallel to the first front face ,and a first lateral surface and second lateral surface that is oriented parallel to the first lateral surface. Furthermore, the vane comprises a first contour surface and a second contour surface. The method for producing the vane comprises at least the following steps: pressing (20) a powder mixture to a green body by means of a powder press , sintering (21) the green body inside a sintering furnace to a sintering element having an austenitic structure , quenching the sintering element inside the sintering furnace to a temperature below the martensitic start temperature for hardening (22) , tempering (23) the sintering element preferably inside the sintering furnace , removing (24) the sintering element as net- shape vane , preferably as removal from the sintering furnace. After removing the sintering element , deburring (25) can optionally be made. The invention further relates to a vane and a rotary vane pump.
