Title: **Nobuhisa Kurono: A Pioneer in Material Innovations**
Introduction
Nobuhisa Kurono is an innovative inventor based in Chita-gun, Japan. With a remarkable portfolio of two patents, he has made significant contributions to the field of material science. His expertise lies in developing advanced surface treatment methods that enhance the performance of various materials.
Latest Patents
Kurono's most recent inventions include a surface treatment method for quartz material and a method of manufacturing aluminum borate whiskers. The surface treatment method involves exposing quartz material to a heat contact treatment with ammonia gas at 1200 degrees Celsius in the presence of a carbon generating source. This process results in the formation of a silicon oxynitride layer on the quartz surface, enhancing its heat resistance. It has been noted that the silicon oxynitride layer shows excellent adhesion, even under repetitive heat cycles. Additionally, a second treatment step involving the application of a silicon nitride film using methods such as CVD further improves the material's heat resistance.
The second patent focuses on the manufacturing of aluminum borate whiskers with a reformed surface. This method aims to produce composite materials with superior strength by minimizing the generation of spinel along the whisker surfaces. It involves heating aluminum borate whiskers, covered with a r-alumina surface layer, in an atmosphere of ammonia gas or a combination of ammonia gas and hydrocarbon gas, resulting in a nitro-oxide and aluminum oxide layer along the whiskers.
