Title: The Innovative Contributions of Donald Williams
Introduction
Donald Williams is a notable inventor based in Kingston, CA. He has made significant contributions to the field of powder metallurgy, holding 2 patents that showcase his innovative methods for manufacturing composite components and thin wall metal components.
Latest Patents
One of his latest patents is titled "Manufacture of composite components by powder metallurgy." This method involves compacting a mixture of a first pre-alloyed powder and a lubricant to form a green part with sufficient green strength for mechanical handling. The process includes applying a slurry to the green part's surface, which consists of a second pre-alloyed powder, a binder, and a solvent. The coated green part is then heated to facilitate solid state sintering of the first powder and liquid state sintering of the second powder, resulting in a sintered core with a continuous alloy coating.
Another significant patent by Williams is "Slurry-based manufacture of thin wall metal components." This method entails applying a slurry to a temporary substrate to create a slurry-coated surface. The slurry contains a Co-, Ni-, or Fe-based material, a binder, and a solvent. After drying the substrate to remove the solvent, the coating layer is heated to eliminate the binder and sinter the metal-based material into a continuous alloy layer, which is then separated from the substrate.
