Title: Innovations of Katsushige Shimizu in Steel Treatment
Introduction
Katsushige Shimizu is a prominent inventor based in Aichi, Japan, renowned for his contributions to the field of steel treatment. With a total of two patents to his name, Shimizu has been instrumental in advancing methods that enhance the durability and performance of steel components. His work is particularly significant in industries that require high-performance materials, where the integrity of steel parts is crucial.
Latest Patents
Shimizu's latest innovations include two notable patents focused on nitriding treatment methods for steel members. The first patent describes a nitriding treatment method where a steel member is subjected to a nitriding gas atmosphere to generate a γ' phase or ε phase iron nitride compound layer on its surface. This process is carefully executed to ensure that the compound layer does not grow beyond five minutes under set temperature conditions, resulting in an uppermost surface layer of the γ' phase with a precipitation ratio of 40% or more in the iron nitride compound layer.
His second patent introduces a continuous nitriding treatment furnace that comprises a nitriding chamber, a heater, and two nitriding zones with varying gas temperatures. This innovative furnace design allows for a precise nitriding treatment, forming an iron nitride compound layer consisting of either ε phase or a combination of ε phase and γ' phase. The gas flow from the first nitriding zone to the second enables a controlled deposition of the γ' phase in the iron nitride compound layer.
