Title: Hiroshi Eiraku: Innovator in Corrosion Resistance Technology
Introduction
Hiroshi Eiraku is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of materials science, particularly in enhancing the corrosion resistance of metal components. His innovative approach has led to the development of a unique method that is both effective and efficient.
Latest Patents
Eiraku holds a patent for a method of producing a metal member with enhanced corrosion resistance through salt bath nitriding. This process involves immersing a metal member in a nitriding salt bath containing lithium, sodium, and potassium ions, along with carbon oxynitride and carbon monoxide ions. The method enhances the oxidizing power of the bath by adding substances such as alkali metal hydroxides, bound water, free water, and moist air. This results in the formation of a nitrided layer on the metal surface, along with an oxide film on the outermost layer of the nitrided layer. Following this immersion, the metal member is further treated in a displacement cleansing salt bath containing alkali metal nitrate.
