Abstract

Artigo e métodos de formação do mesmo Um método para consolidar materiais articulados em artigos tendo combinações de propriedades não disponíveis por processos convencionais por sinterização em fase líquida. Estes materiais particulados são compreendidos de partículas de núcleo individualmente revestidas com camadas de um composto metálico tendo uma resistência à fratura relativamente mais elevada do que o núcleo, tal como WC ou TaC. Estas partículas revestidas incluem uma camada exterior compreendida de um metal, tal como Co ou Ni. As partículas com estas camadas são comprimidas para formar um artigo e o artigo tornado denso a pressões e temperaturas em que a densidade plena é alcançada sem a degradação do material que forma a partícula do núcleo.Article and Methods of Forming It A method for consolidating articulated materials into articles having combinations of properties not available by conventional liquid phase sintering processes. These particulate materials are comprised of individually layered core particles of a metal compound having a relatively higher fracture resistance than the core, such as WC or TaC. These coated particles include an outer layer comprised of a metal, such as Co or Ni. Particles with these layers are compressed to form an article and the article is dense at pressures and temperatures at which full density is achieved without degradation of the core particle forming material.
