Title: Yoshiaki Yamamoto: Innovator in Solid Lubricants
Introduction
Yoshiaki Yamamoto is a prominent inventor based in Fujisawa, Japan. He has made significant contributions to the field of solid lubricants, holding a total of 5 patents. His innovative work focuses on developing materials that enhance the performance and durability of sliding members in various applications.
Latest Patents
Yamamoto's latest patents include a solid lubricant and a sliding member that incorporates this lubricant. The solid lubricant features a low friction coefficient and excellent abrasion resistance. It consists of a sea-island structure, where the sea phase is a continuous phase made up of hydrocarbon-based wax and polyethylene resin. The island phase is a dispersion phase that includes low-molecular weight tetrafluoroethylene resin, higher fatty acid salt, phosphate of a basic nitrogen-containing compound, and zinc stannate. Additionally, a high-molecular weight tetrafluoroethylene resin is present in a fibrous and mesh state within the continuous-phase sea. The specific compositions of these materials are carefully balanced to achieve optimal performance.
Another notable patent involves a solid lubricant designed to be embedded in the pores or grooves of a sliding member body. This lubricant comprises 5 to 30% by volume of polyethylene resin, 20 to 60% by volume of hydrocarbon-based wax, and 10 to 60% by volume of melamine cyanurate. This formulation allows the solid lubricant to exhibit sliding properties that are comparable to or even superior to those of traditional lead-containing lubricants, even under high load conditions.
