Abstract

Processo de brasagem por microondas. é descrito um processo para o aquecimento de uma liga de brasagem, através de uma radiação de microondas (26), de tal forma que o aquecimento da liga é seletivo e suficiente de modo a causar a fusão completa da liga e assim permitir uma ligação metalúrgica com o substrato (14) sobre o qual a liga é fundida, mas sem um aquecimento excessivo do substrato (14) de modo a não degradar as propriedades do substrato (14). A invenção compreende fornecer partículas (12) na forma de um pó metálico, essencialmente apresentando a mesma composição metálica, com ao menos algumas dentre as partículas (12) sendo pequenas o suficiente de modo a serem altamente susceptíveis a radiação em microondas (26). A massa (10) das partículas (12) é então aplicada a uma superfície do substrato (14), após o que a massa (10) é submetida a uma radiação em microondas (26) de tal forma que as partículas (12) dentro da massa (10) se acoplem com a radiação em microondas (26) e fundam de forma suficiente de modo a se ligarem metalurgicamente ao substrato (14). A radiação em microondas (26) é então interrompida e a massa (10) é deixada até resfriar, se solidificando, e formando uma brasagem sólida.
