Title: Innovations by Yuta Dairokuno: Advancements in Surface-Treated Steel Sheets
Introduction
Yuta Dairokuno is an accomplished inventor based in Tokyo, Japan, known for his significant contributions to the field of materials engineering. With a total of three patents to his name, his work focuses primarily on the development of advanced surface-treated steel sheets, which have a substantial impact on various industrial applications.
Latest Patents
Dairokuno's latest innovations include two patents for surface-treated steel sheets. The first patent outlines a surface-treated steel sheet that consists of a steel substrate and an alloy layer containing nickel (Ni) and cobalt (Co) on its surface. Notably, the surface roughness Ra1 of the alloy layer is 2.0 μm or less over a 5.0 mm sampling length, while the arithmetic mean height of roughness Ra2 is 20 nm or less over a 10 μm sampling length. Furthermore, the mean length of roughness curve elements, RSm, measures 700 nm or more, all characterized using atomic force microscopy.
The second patent describes an innovative surface-treated steel sheet featuring an Ni—Co—Fe alloy layer. In this design, the cobalt concentration is highest near the outermost surface of the alloy layer, while the nickel concentration peaks at a depth of approximately 100 nm from the outermost surface. This arrangement creates a unique Ni-concentrated region that enhances the properties of the alloy layer.
