Abstract
Processo de moldagem por injeção de metal para aplicações em bi-metálicos e aerofólio. é descrito um método para a produção de um aerofólio (12), incluindo as etapas de fornecer uma primeira preforma (32), a qual é formada por um pó metálico de uma primeira liga, a primeira preforma definindo um corpo de aerofólio apresentando lados curvos de pressão e de sucção (20, 22). Uma cobertura de ponteira (28) é disposta entre os lados de pressão e de sucção em uma extremidade radialmente externa do corpo do aerofólio. Uma ponteira indicadora (30) de altura parcial se estende radialmente para fora a partir da cobertura de ponteira de modo a fornecer uma segunda preforma (34) formada de um pó metálico de uma segunda liga, diferente da primeira liga. A cobertura de ponteira apresenta a forma de uma extensão da ponteira indicadora. A primeira e a segunda preformas são sinterizadas para consolidar os pós metálicos. Também é descrito um aerofólio produzido de acordo com este método.
