He holds two patents that focus on enhancing the properties of rare earth metal-transition metal magnets. His work has significant implications for various applications requiring durable and efficient magnetic materials.
Latest Patents
Kitano's latest patents include innovations in corrosion-resistant rare earth metal-transition metal series magnets. The first patent describes a method for creating permanent magnets that excel in both magnetic properties and corrosion resistance. This invention utilizes two magnetically useful phases, specifically the RE.sub.2 TM.sub.14 B phase, which has a high residual magnetic flux density, and a low melting point RE-TM' phase or RE-TM'-B phase. This combination enhances sinterability and provides a cleaning action against grain boundaries of the main phase. The second patent focuses on a corrosion-resistant rare earth metal-transition metal-boron permanent magnet. This magnet features improved corrosion resistance and excellent magnetic properties, comprising RE at 10-25 at % (where RE includes Y, Sc, and lanthanides), B at 2-20 at %, with the remainder being primarily Fe, Co, and Ni. The magnet also has an average crystal grain size of 0.1-50 µm and includes a crystal grain boundary phase of RE(Ni.sub.1-x-y Co.sub.x Fe.sub.y) compound.
