    摘要: The invention relates to a method for producing a homogeneous mixture of hard material powders and binder metal powders without using grinding bodies, liquid grinding auxiliary agents and suspending media. According to the invention, the mixture components are mixed at close range while generating a high shearing collision velocity of the powder particles and are remotely mixed by rotating the mixing bed without resulting in a particle size reduction of the hard material powders.

    摘要: The present invention relates to a metal powder mixture that is suitable for producing sintered bodies. The powder mixture is suitable as a binder for hard metals and contains: a) at least one prealloyed powder selected from the group of iron/nickel, iron/cobalt, iron/nickel/cobalt and nickel/cobalt; b) at least one element powder selected from the group of iron, nickel and cobalt or a prealloyed powder selected from the group consisting of iron/nickel, iron/cobalt, iron/nickel/cobalt and nickel/cobalt which is different from component a). The invention also relates to a cemented hard material which uses the inventive powder mixture and a hard material powder, wherein the overall composition of the components a) and b) together contains not more than 90% by weight of cobalt and not more than 70% by weight of nickel and the iron content.

    摘要: The invention concerns metal powder granulates comprising one or a plurality of the metals Co, Cu, Ni, W and Mo. The invention further concerns a method for the production of these granulates and the use thereof. The production method is characterized in that a metal compound comprising one or a plurality of the groups comprising oxides, hydroxides, carbonates, hydrogenocarbonates, oxalates, acetates, formiates with binder and optionally in addition between 40 and 80% solvent, relative to the solids content, is granulated as the starting component, and the granulates are thermally reduced in a hydrogen-containing gaseous atmosphere to form the metal powder granulates, the binder and the solvent, if used, being removed completely.
