Latest Patents
Koyanagi holds a patent for a "Wear resistant sintered member." This invention exhibits superior wear resistance comparable to conventional materials, but without the use of a cobalt-based hard phase. The design includes a first hard phase comprising molybdenum silicide particles dispersed in an iron-based alloy matrix, and a second hard phase that consists of a ferrite phase or a mixed phase of ferrite and austenite. This second phase has a higher chromium concentration than the iron-based alloy matrix, surrounding a core of chromium carbide particles. The molybdenum silicide particles are contained in the first hard phase in an amount of 3 to 25% by area, while the chromium carbide particles are contained in the second hard phase in an amount of 3 to 30% by area. Koyanagi's innovative design addresses the need for enhanced wear resistance in various industrial applications.
