Title: Shizuo Matsushita: Innovator in Valve Technology
Introduction
Shizuo Matsushita is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of valve technology, holding a total of 5 patents. His work focuses on enhancing the performance and durability of valves through innovative materials and manufacturing methods.
Latest Patents
Matsushita's latest patents include a valve and manufacturing method that emphasizes cobalt-free materials. This valve is designed to exhibit excellent wear resistance and seizure resistance. The manufacturing process involves forming valve seats for a valve disc and a valve body using a nickel base alloy, which contains finely dispersed silicide or boride particles. The bonding of the valve seat to the valve disc or body is achieved through transient liquid phase diffusion bonding with an insert material of a nickel base alloy that has a lower melting point.
Another significant patent involves the joint construction of cobalt-based alloys. In this method, a cobalt-based alloy layer, which contains granular or massive eutectic carbide, is joined to a base metal using an insert metal layer. The process requires liquid phase diffusion bonding at a temperature of 1100°C for one hour, utilizing an insert metal of approximately 40 micrometers in thickness. The cobalt-based alloy material is characterized by its specific composition, which includes 1.03 wt % C, 29.73 wt % Cr, 3.86 wt % W, 2.59 wt % Ni, 2.67 wt % Fe, 0.59 wt % Si, and 0.07 wt % Mo, with cobalt being the balance.
