Abstract

"PROCESSO DE PRENSAGEM úNICA E SINTERIZAçãO úNICA PARA A PRODUçãO DE ARTIGOS SINTERIZADOS, FERRAMENTA PARA COMPRESSãO DE Pó METáLICO PARA FORMAR COMPACTOS PARA SINTERIZAçãO, E, ARTIGO SINTERIZADO" A presente invenção refere-se a uma ferramenta de compressão de pó metálico para formar compactos para sinterização, incluindo uma primeira punção (15) adaptada para comprimir pó localizado em uma matriz (10). A folga entre a punção e a matriz é maior do que a expansão radial da punção sob o esforço de compressão desejado, e menor do que o tamanho médio do grão do pó.
