Title: Shoji Shijima and Corrosion-Resistant Tin-Plated Steel
Introduction
Shoji Shijima is an inventor associated with Chiba, Japan, and Kawasaki Steel Corporation. His patent work addresses the corrosion resistance of tin-plated steel sheet.
Latest Patents
The available information lists one patent for Shijima: “Method of Producing Highly Corrosion Resistant Tin-Plated Steel Sheet.” The method first plates steel with a thin coating of nickel, copper, or a nickel-tin alloy, then heats the sheet in a non-oxidizing atmosphere so the coating diffuses into the steel surface. Tin is subsequently plated onto the reformed surface. The resulting intermediate surface layer is intended to improve the corrosion resistance of the tin-plated steel sheet. Shijima is credited with 1 patent.
Career Highlights
Shijima’s listed invention focuses on improving the performance of tin-plated steel through surface treatment and diffusion. His work is associated with Kawasaki Steel Corporation.
Collaborations
Taketoshi Fujimaki and Shunichi Harada are identified as Shijima’s coworkers.
Conclusion
Shoji Shijima’s patent describes a steel-sheet production method that uses a diffused surface layer beneath tin plating to enhance corrosion resistance.
