Abstract

Inventia se refera la un procedeu pentru alierea si modificarea chimica sau structurala a unei anumite parti din piesele turnate din aliaje feroase sau neferoase, permitînd obtinerea unor asemenea straturi încît piesele respective sa prezinte o comportare corespunzatoare în exploatare. în interiorul cavitatii formei de turnare, în zona în care masa de metal de baza se doreste a se modifica structural sau chimic pe o anumita adîncime, se utilizeaza un strat de modificator sub forma granulara, supus actiunii unei depresini pe toata durata procedeului de turnare.
