Title: Katsuhiro Kishida: Innovator in Aluminum Alloys and Welding Technologies
Introduction
Katsuhiro Kishida is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the fields of materials science and engineering, particularly in the development of aluminum alloys and welding technologies. With a total of 7 patents to his name, Kishida's work has had a lasting impact on various industries, including automotive manufacturing.
Latest Patents
One of Kishida's latest patents is for an aluminum base bearing alloy and method of producing the same. This invention provides an aluminum base bearing alloy that excels in both lubricating capability and fatigue resistance, making it particularly useful in automotive engines. The alloy consists of at least one lubricating element, such as lead (Pb) and/or tin (Sn), with a total amount exceeding 0.04 and not more than 0.07 by sectional area ratio to the aluminum matrix. Additionally, it includes silicon (Si) in the range of 0.01 to 0.17 by sectional area ratio, along with 0.2-5.0 wt % of at least one reinforcing element like copper (Cu) and/or chromium (Cr). The production process involves preparing a raw material alloy powder mixture, compacting it into a billet, and extruding the billet at an extrusion ratio not lower than 10.
Another notable patent is for a welding wire designed for automatic arc welding. This welding wire is particularly suitable for build-up welding operations aimed at providing a hard surface to metal dies. The wire consists of a continuous tubular metal casing and a core composition that includes essential alloying elements such as nickel (Ni), silicon (Si), boron (B), niobium (Nb), and carbon (C). The deposited metal from this welding wire exhibits high wear resistance and good antifrictional properties, minimizing the occurrence of weld cracks.
