Abstract

A method for treating a piece () made of a first porous material () with a second material () when this second material is in liquid state, said second material () being suitable for infiltration when a predetermined temperature range (DTi) and a predetermined field of infiltration pressure (Dpi), comprises the steps of: —providing a crucible () suitable for containing the piece () and the second material () and capable of withstanding the temperatures and pressures for the infiltration of the second material () in the piece (); providing a cover () for the crucible () suitable for closing the crucible creating a chamber () inside the crucible; placing the piece () and the second material () in said crucible chamber (), when this second material is not yet in liquid state; —subsequently closing the crucible () with the cover (); —at a pressure (pa or pa1)—unsuitable for the infiltrations of the second material in the first porous material, raising the temperature of the piece () and the second material () contained in the crucible up to a predetermined temperature (T) suitable for liquefying said second material () for making it suitable for infiltration in said piece () made of first porous material; —subsequently, lowering the pressure to a predetermined pressure value (p) lower than the previous pressure (pa or pa1) and allow the infiltration of the second material () in said piece () made of first porous material ().
