Abstract

Inventia se refera la un procedeu d eobtinere a formelor si miezurilor de turnatorie, utilizate pentru turnarea pieselor din otel. Procedeul utilizeaza monofosfatul de aluminiu ca impregnant, în vederea cresterii reziatentei mecanice si termice a miezurilor si formelor, eliminând astfel defectele de suprafata ale pieselor turnate.
