Title: Mitsuo Kuwabara: Innovator in Forging Die Technologies
Introduction
Mitsuo Kuwabara, based in Tsurugashima, Japan, is a celebrated inventor with an impressive portfolio of 27 patents. His work primarily focuses on enhancing the durability and performance of forging dies through innovative coating and treatment methods. As a pivotal figure in the field of metallurgy, Kuwabara's contributions are instrumental in advancing manufacturing technologies.
Latest Patents
Kuwabara's recent patents include a die reinforcing method and a die repairing method. The die reinforcing method involves applying a mixed powder layer to a cavity of a forging die made of an iron-base alloy. This mixed powder comprises a first element capable of forming a carbide, which enhances the die's hardness, and a second element with a lower melting point. The process utilizes the heat generated during forging to reflow the layered materials, diffusing the carbide throughout the die, thereby reinforcing it.
Another notable patent describes a method for preparing steel material, where raw steel is treated with a boron compound to form a coating film of hexagonal Boron Nitride (h-BN) on its surface. Subsequent nitriding introduces Boron and Nitrogen into the steel, creating a composite material that incorporates these elements in solid solution forms, significantly improving its mechanical properties.
