Title: Inventor Tomotake Hirata: A Pioneer in Friction Stir Processing

Introduction

Tomotake Hirata, an innovative inventor based in Osaka, Japan, has made significant contributions to the field of friction stir processing. With two patents to his name, his work has helped advance the technology used for processing metal materials.

Latest Patents

Hirata's latest patents include a friction stir processing apparatus and a friction stir processing method. The friction stir processing apparatus features a tool, a processing head, a support table, and a cylinder unit that biases the support table toward the tool. The design incorporates a probe that projects from the shoulder surface of the tool, enabling effective friction stir processing on various metal workpieces. The unique load control means constantly manages the bias force of the cylinder unit, ensuring consistent pressurizing force on the tool, which significantly enhances the quality of processing, even when dealing with workpieces of varying thickness or materials.

Additionally, his friction stir processing tool comprises a Ni-based dual multi-phase intermetallic compound alloy containing rhenium (Re). This alloy is generally formed through casting and is heat treated post-casting to improve performance. The method utilizes friction heat generated from the rotating tool pressed against the workpiece, softening the material for processing. The high hardness of the Ni-based alloy exhibits exceptional abrasion resistance, enabling durability for extended friction stir processing applications.
