HIPProzess für offen porösen Stahl X20Cr13

Last stage rotor blades of low pressure steam turbines are still being under consideration. In order to increase the effectiveness of the low pressure turbine a new open porosity powder metallurgical composite should be developed, so that the condensed water could be sucked off over the whole surface instead of locally via slots. To this end chromium steel powder for the carrier material and the porous surface layer is combined with place holder material for the suction ducts. The open porous layer is formed from mixtures of chromium steel powder and pure iron powder and different salts as place holder powder. After hot isostatic pressing the powder metallurgical composite, the dummy material, which is used to finally yield the porosity in the composite, is be leached out. In different experiments the manufacturing parameters are established.
