Abstract:
A method for producing a powder-metallurgical product, in particular a bearing element or a motor component, is provided. According to the method, a metal powder, typically with a grain size between 2 μm and 15 μm, is melt-metallurgically produced and agglomerated into a powder mixture having a grain size smaller than 400 μm by organic binders and waxes. Subsequently, the agglomerated powder mixture is formed into a green body typically by way of uniaxial pressing and the formed green body thermally debindered. Finally, the debindered green body is sintered typically at temperatures of 1000° C. to 1300° C. and the sintered body reworked into the powder-metallurgical product.
