Abstract
Un metodo per la cementazione carburante gassosa di prodotti in acciaio comprende il trattamento termico in forno dei prodotti sotto pressione parziale di uno o più idrocarburi per consentire l'assorbimento di atomi di carbonio negli strati superficiali dell'acciaio.Il trattamento viene condotto in una atmosfera formata da idrocarburi e gas inerte mantenendo l'atmosfera stessa a pressione assoluta maggiore o uguale alla pressione atmosferica e viene controllato mediante rilevazione quantitativa di uno o più dei componenti dell'atmosfera gassosa in entrata e/o in uscita dal forno.
