Title: Innovations of Hiroshi Kumon
Introduction
Hiroshi Kumon is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced sintering methods and composite metal castings. With a total of 3 patents, his work has had a considerable impact on manufacturing processes.
Latest Patents
Kumon's latest patents include a sintering method for making a high carbon ferrous sliding element. This innovative method consists of two principal stages. The first stage involves sintering green compacts in a regular manner. The second stage follows immediately, where the sintered compacts are held for a set time at an elevated temperature below the sintering temperature in carburizing gas. This process allows for the diffusion of essential components, such as carbon, into the compacts, particularly for ferro-carbide compacts used as sliding elements. Additionally, his method of making a composite metal casting involves interlocking a steel plate with aluminum material. This is achieved by forming teeth on the steel plate's surface, which creates primary interstices. The molten aluminum material penetrates these interstices, ensuring a firm bond upon solidification.
