Abstract

método para produção de produtos de metal duro a presente invenção está correlacionada a um método para produção de peças de metal duro à base de carbeto cementado, compreendendo constituintes duros em uma fase aglutinente, mediante uso de moldagem por injeção de pó ou extrusão de uma mistura de constituintes duros e uma fase aglutinante em aglutinantes orgânicos que apresentam ponto de fusão, o método compreendendo as etapas de: - misturar os pós de constituintes duros e a fase aglutinante, de modo a formar uma mistura; - aquecer a dita mistura de constituintes duros e fase aglutinante a uma determinada temperatura; - quando a temperatura da mistura de constituintes duros e fase aglutinante se encontrar acima do ponto de fusão dos aglutinantes orgânicos, adicionar os aglutinantes orgânicos na forma fundida, tendo a certeza de que a temperatura não irá cair abaixo do ponto de fusão aglutinantes orgânicos; - formar as peças mediantes moldagem por injeção de pó ou extrusão; - remover os aglutinantes orgânicos das peças obtidas mediante uma etapa de desaglutinação; e - sinterizar as peças.
