Title: Kevin J Jakubenas: Innovator in Refractory Metal Carbides
Introduction
Kevin J Jakubenas is a notable inventor based in Austin, TX, who has made significant contributions to the field of materials science. He holds 2 patents that showcase his innovative approaches to producing refractory metal carbides and joining solid compositions.
Latest Patents
One of Jakubenas's latest patents is a reaction-forming method for producing near net-shape refractory metal carbides. This method involves fabricating a glassy carbon preform by casting an organic, resin-based liquid mixture into a mold and subsequently heat treating it in two steps. The process cures and pyrolizes the resin, resulting in a porous carbon preform. By varying the amounts of constituents in the organic mixture, he achieves control over the density of the carbon preform, which in turn influences the microstructure and properties of the resulting refractory metal carbide material. The glassy carbon preform is then placed on a bed of refractory metal or a refractory metal-silicon alloy, where it is heated above the melting point, allowing the molten metal to wick inside the porous carbon and react to form the desired carbide.
Another significant patent involves a process for joining ceramics and attaching fasteners to solid compositions using a gas phase. This innovative process includes placing two solid compositions in a chamber and positioning a gas phase that decomposes to adhere to both compositions. An energy beam is directed to selectively deposit material from the gas phase, forming a joint between the two solid compositions. This method is also applicable for repairing defects in solid compositions, such as chips or cracks.
