Title: Kazuo Fujii: Innovator in Powder Metallurgy
Introduction
Kazuo Fujii is a notable inventor based in Ohmihachiman, Japan. He has made significant contributions to the field of powder metallurgy, holding a total of 4 patents. His innovative work focuses on enhancing the properties of aluminum products through advanced manufacturing methods.
Latest Patents
Fujii's latest patents include a raw material for powder metallurgy and a nitriding agent. The raw material for powder metallurgy is designed to contain at least 0.5 vol % and at most 10 vol % of alumina powder, with specific sieve fraction requirements. This formulation minimizes particle agglomeration, resulting in a highly reliable raw material that exhibits superior fatigue strength, impact resistance, and wear resistance. The preparation method involves air classifying the powder materials, dry ball mixing, and annealing the mixed powder.
His nitriding agent patent describes a process for producing a case nitrided aluminum product. This involves contacting an aluminum product with a nitriding agent at a surface part and nitriding it with an ambient gas at a temperature below the melting point of aluminum. The resulting nitriding layer achieves a depth of 5 micrometers or more, providing a case hardness ranging from 250 to 1,200 mHv. This innovation allows for the creation of sliding parts that require high wear resistance.
