Abstract

Fremgangsmåte for konsolidering av partikkelformede materialer til gjenstander med kombinasjoner av egenskaper som ikke er tilgjengelige med konvensjonelle behandlinger med flytfasesintring. Disse partikkelformede materialer består av kjemepartikler som hver belegges med lag av en metallsammensetning med en relativt høyere sprekkfasthet enn kjernen, så som WC eller TaC. Disse belagte partikler har et ytie lag bestående av et metall, så som Co eUerNi. Partiklene med disse beleggene bhr presset for dannelse av en gjenstand, og gjenstanden fortettes under trykk og temperaturer hvor det oppnås fuU tetthet uten en degradering av materialet i kjemepartiklene.Method of consolidating particulate materials into articles with combinations of properties not available with conventional liquid phase sintering treatments. These particulate materials consist of core particles, each coated with layers of a metal composition having a relatively higher crack strength than the core, such as WC or TaC. These coated particles have a surface layer consisting of a metal, such as Co or Ni. The particles with these coatings are pressed to form an article, and the article is densified under pressure and temperatures where full density is achieved without degrading the material in the core particles.
