  • Vacuum pressure transformation vessel and method of use
    Patent number: 11180422
    Abstract: A method of forming a ceramic-metal composite part is described herein. The method includes maintaining molten metal in an interior of a housing in a liquefied state, the interior including a first chamber, a second chamber, and a port defined therebetween. The method further includes sealing the port such that the molten metal in the first chamber is maintained at a first liquid level, suspending a part at a height within the first chamber above the first liquid level, forming a pressure differential between the first chamber and the second chamber, unsealing the port such that molten metal from the second chamber flows into the first chamber, and resealing the port when the molten metal in the first chamber reaches a second liquid level such that the ceramic part is submerged in the molten metal.
