Latest Patents

One of his latest patents is focused on "Infiltrated Aluminum Preforms." This method involves the manufacture of a three-dimensional object through a series of steps. It begins with forming a mixture that contains a binder and at least one of aluminum or a first aluminum-base alloy into a green composite. The binder is then removed from the green composite, leading to the formation of a porous preform structure. The aluminum or first aluminum-base alloy reacts with nitrogen to create a rigid and continuous skeleton. Finally, the porous structure is infiltrated with molten aluminum or a second aluminum base alloy, resulting in a three-dimensional object with near theoretical density. This method facilitates the rapid manufacture of aluminum components using an inexpensive technique that ensures high dimensional stability and density.
