Abstract

"REFINO DE METAIS E LIGAS REFRATáRIOS POR FORMAçãO E FUSãO A LASER". Um processo para refinar e consolidar, quimicamente tântalo, nióbio e as suas ligas a um produto fabricado de forma final ou forma próxima da final, com rendimento mais alto, mais consistência e custos de produção mais baixos, comparado com as rotas da temperatura ambiente, ou de rejuvenescimento de peças de metais refratários danificados e deteriorados. O pó metálico é carregado nos alimentadores, para que seja alimentado no equipamento de formação/fusão a laser. Um substrato adequado é carregado em uma câmara de formação/fusão a laser, na qual o pó vai ser depositado e consolidado em um processo de varredura pontual. Na medida em que o pó é alimentado em pontos sucessivos da superfície do substrato em traços lineares, o laser é usado para aquecer e fundir parcialmente o substrato e fundir completamente o pó. Uma deposição e aplicação de feixe de fusão combinadas traçam a superfície do substrato repetidamente por uma área selecionada, para produzir um revestimento denso de microestrutura controlada em camadas múltiplas. Um depósito inteiramente denso é produzido que assume a forma desejada.
