Title: Innovations in Corrosion Resistance by Yasumi Ariyoshi
Introduction
Yasumi Ariyoshi is a notable inventor based in Sakai, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced steel sheets with improved corrosion resistance. With a total of 3 patents to his name, Ariyoshi's work is recognized for its innovative approaches to enhancing the durability of steel products.
Latest Patents
Ariyoshi's latest patents include a chemically processed steel sheet that significantly improves corrosion resistance. This new processed steel sheet features a steel base coated with a zinc or its alloy plating layer, along with a converted layer that contains both insoluble or scarcely-soluble metal compounds and soluble metal compounds. The insoluble compounds serve as a barrier, insulating the steel base from the atmosphere, while the soluble compounds provide a self-repairing capability for any defects in the converted layer. This innovation eliminates the need for chromium compounds, which can be harmful to the environment.
Another notable patent involves a steel sheet coated with a zinc-magnesium (Zn-Mg) binary coating layer. This coating has a tri-layered structure, with varying magnesium concentrations in each sublayer. The design ensures excellent adhesion and enhances the intrinsic properties of the high-magnesium sublayer. As a result, the coated steel sheet is particularly useful for structural members or parts exposed to severe corrosive environments in various industrial applications.
