Title: The Innovations of Masaki Takashima
Introduction
Masaki Takashima is a notable inventor based in Urawa, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced alloys. With a total of two patents to his name, Takashima's work showcases his expertise and innovative spirit.
Latest Patents
One of Takashima's latest patents is for a plated nickel-titanium alloy product. This product features a plated layer of nickel or a nickel alloy containing 5 to 15% by weight of cobalt. It exhibits excellent surface treatability and workability, along with a remarkable shape memory effect and super-elasticity. This makes it particularly suitable for eyeglass frame components and similar ornamental articles. The production process involves plating a layer of nickel or a nickel-cobalt alloy on the nickel-titanium alloy, followed by dehydrogenation, cold working with a minimum of 10% working ratio, and a final heat treatment between 300°C and 900°C. Notably, if the final heat treatment is conducted between 750°C and 900°C for 10 to 120 seconds, a product with 4% or more super-elasticity at room temperature can be achieved.
Another significant patent by Takashima is for a nonmagnetic ferrous alloy with excellent corrosion resistance. This Ni-free ferrous nonmagnetic alloy boasts high cost performance and workability. It comprises, by weight, 9 to 25% chromium, 3 to 35% manganese, and 3 to 40% cobalt, with the balance being iron and incidental impurities. The sum of manganese and 0.6 times cobalt adheres to specific general and restricted relationships, enhancing its performance.
