Latest Patents
Tujimoto's latest patents focus on the formulation of copper-based sliding materials. One of his inventions includes a copper-based sliding material that features a steel back-metal layer and a Cu alloy layer. This Cu alloy layer contains, by mass %, 10 to 30% of Bi, along with 0.5 to 5% of an inorganic compound, with the remainder being Cu and inevitable impurities. The inorganic compound is characterized by an average particle size of 1 to 5 µm and a specific gravity of 70 to 130% relative to Bi. Additionally, the Bi phase is formed in the Cu alloy layer with an average particle size of 2 to 15 µm, ensuring isotropic dispersion.
Another patent by Tujimoto describes a copper-based sliding material where the Cu alloy layer contains 5% to 30% by mass of Bi. In this formulation, Bi is dispersed as particles of a Bi phase, with a mass ratio of particles having a size of 2 to 50 µm and a circularity of 0.1 to 0.7 being 30% or more. This design allows for improved seizure resistance as the particles of the Bi phase are sequentially exposed to the sliding surface during wear.
