Abstract

Pré-formas por processo de MIM para brasagem. Um método para a produção de uma preforma (52), inclui: fornecer uma mistura entre uma liga de brasagem na forma de um pó metálico e entre um ligante; fundir o ligante e conformar a mistura como uma preforma (52) apresentando um formato pré-selecionado; remover a maioria do ligante da preforma (52); e aquecer a preforma (52) para remover o restante do ligante e para sinterizar o pó metálico junto. A preforma (52) pode incluir um material resistente ao desgaste nesta. Tais pré-formas (52) podem ser usadas de modo a formar uma união por brasagem entre dois componentes metálicos, ou para produzir um componente metálico com uma superfície resistente ao desgaste.
