Verfahren zur Herstellung von Hartmetallbauteilen

Production of hard metal components comprises mixing a hardmetal powder of average grain size of less than 2 mu m with a liquefied thermoplastic binder and processing the stably dispersed suspension into a moulding, from which the binder is removed and the moulding is sintered. The novelty is that the viscosity of the mixture of hard metal powder and liquefied binder is adjusted to 100-2000 mPa.s during the total production and processing. USE - The components are used as processing tools and wear elements. ADVANTAGE - The primary particles in the suspension are stabilised and loss of homogeneity of the mixture is prevented.
