Johnson, an accomplished inventor based in River Falls, Wisconsin, has significantly contributed to the field of metallurgical powder composition through his innovative ideas and methodologies. With a total of three patents to his name, Johnson has demonstrated a commitment to advancing the capabilities of metal processing.
Latest Patents
Johnson's latest patents include a "Method of Making Lubricated Metallurgical Powder Composition" and a "Method of Producing Metal Coatings on Metal Powders." The first patent focuses on a technique for integrating a lubricant and sintering aids with iron-based powders. This method enhances the strength properties of the resulting compacted and sintered materials. The innovation involves contacting a particulate iron-based powder with a solution of a metal salt of a fatty acid in an organic solvent, which, upon removal of the solvent, yields self-lubricated powder compositions.
His second patent, "Method of Producing Metal Coatings on Metal Powders," presents a process for creating compressible and sinterable metal-coated powders. This involves treating core metal particles with a sol containing a precursor coating metal. The effective viscosity of the sol allows for the formation of a uniform coating layer on the core particles upon drying and conversion of the precursor.
