Latest Patents
Pecnenik holds a patent for the "Densification of ceramic-metal composites." This patent describes a method for preparing substantially dense, void-free ceramic-metal composites from components that exhibit chemical incompatibility and non-wetting behavior. The resulting composites maintain a final chemistry similar to the starting materials and feature microstructures characterized by ceramic grains comparable in size to the initial powder, along with the presence of a metal phase. The method involves forming a homogeneous mixture of ceramic and metal, heating it to a temperature just below the metal's flow point, and applying significant pressure to achieve compaction and densification. This process also induces a temperature spike that exceeds the metal's flowing temperature, further enhancing the composite's density while preventing significant reactions between the metal and ceramic.
