Masanobu Irie

Title: Masanobu Irie: Innovator in Plasma Spraying Technology

Introduction

Masanobu Irie is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the field of plasma spraying technology, holding a total of 3 patents. His innovative designs have advanced the capabilities of plasma spraying apparatuses, making them more efficient and effective.

Latest Patents

One of his latest patents is a plasma spraying apparatus that includes a cathode, a first gas nozzle defining a first gas path, a second gas nozzle defining a second gas path, and a third gas nozzle positioned between the first and second nozzles. This design allows for a wire to be disposed at the distal end in front of the nozzle opening of the second gas nozzle. The first gas, when sprayed through the first gas nozzle, is turned into a plasma flame that melts the wire into droplets. These droplets are then sprayed onto a target by a second gas sprayed through the second gas nozzle. The third gas absorbs heat from the plasma flame, transforming into a high-temperature gas flow externally of the plasma flame.

Another patent by Irie describes a plasma spraying apparatus that features a cathode surrounded by a first gas nozzle, which forms a first gas path outside the cathode. A second gas nozzle surrounds the first gas nozzle, creating a second gas path. This second gas nozzle is designed with a wire path that allows a wire to be inserted, with its distal end positioned in front of the nozzle opening. The wire path has a rectangular cross-section, enabling the wire to bend within its elastic limit, enhancing the efficiency of the plasma spraying process.
