Title: Innovations of Koichiro Koyama
Introduction
Koichiro Koyama is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of materials science, particularly in the development of methods for enhancing the durability of transition metals.
Latest Patents
Koyama holds a patent for a method of boronizing transition metal surfaces. This innovative method is designed to prepare a boride layer on a transition metal substrate, making it suitable for use in corrosive environments or as a hardened surface in machine applications. The process involves preparing a melt of an alkali metal boride tetrafluoride salt, such as KF, to lower its melting point. A boron-containing material, like NiB, MnB₂, or CrB₂, is dissolved in this melt. The transition metal to be coated is then immersed in the melt at a temperature not exceeding 700°C, resulting in the formation of a surface boride layer within approximately 24 hours.
