Abstract
"PROCESSO PARA JUNçãO DE ELEMENTOS METáLICOS SINTERIZADOS EM FORMA DE CHAPA FINA, E CORPO FILTRANTE DE METAL SINTERIZADO COM CAVIDADES FILTRANTES FECHADAS POR JUNçãO NA EXTREMIDADE DE ENTRADA E/OU DE SAìDA DE CORRENTE". Descreve-se um processo para junção de elementos metálicos sinterizados em forma de chapa fina (1), que são formados por um suporte, que é dotado de aberturas enchidas com metal sinterizado e é usado para produzir um elemento filtrante de metal sinterizado (8) e/ou um corpo filtrante de metal sinterizado (7). O processo inventivo é caracterizado pelo fato da porosidade nas áreas de material (6, 14) delimitando a zona de junção (5, 12) de um elemento metálico sinterizado ser reduzida, pela introdução de partículas de granulometria fina, que resistem a temperaturas predominantes durante o processo de junção subseq³ente, dentro do espaço dos poros das ditas áreas de material (6, 14) delimitando a zona de junção (5, 12), antes do processo de junção ser realizado. Descreve-se também um corpo filtrante de metal sinterizado, que é feito do dito elemento metálico sinterizado e compreende cavidades filtrantes (9), cujas extremidades são fechadas no lado de entrada e no lado de saída, por meio de uma junção. Dito corpo filtrante de metal sinterizado é caracterizado pelo fato de, pelo menos, um fechamento localizado em uma de suas extremidades ser dotado de uma área de junção (12), que é delimitada por uma área de material (14) compreendendo um espaço oco poroso, que é cheio com partículas de granulometria fina.
