Abstract

Viene descritto un procedimento per la realizzazione di lamiere metalliche e/o ceramiche ottenute per sinterizzazione di polveri, in cui sono previste le seguenti fasi in successione:(a) preparazione di almeno una miscela composta da polveri metalliche e/o ceramiche associate a polimeri;(b) estrusione della miscela nella sezione e lunghezza volute;(c) termoformatura per compressione diretta del materiale estruso;(d) pirolisi del manufatto termoformato con sostanziale eliminazione della frazione polimerica ed ottenimento di un semilavorato sinterizzato in metallo e/o ceramica.
