With an impressive portfolio of 21 patents, Takahashi’s innovations are recognized for their practical applications in the automotive industry and beyond.
Latest Patents
Among Takahashi's recent advancements are two notable patents focused on iron-based sintered alloy materials for valve seats. The first patent details an iron-based sintered alloy material specifically designed for valve seats, which enhances wear resistance while minimizing aggressibility towards mating valves. This material incorporates a combination of two types of hard particles: the first ones, made of cobalt-based intermetallic compounds, are present in sizes ranging from 10 to 150 μm and exhibit significant hardness. The second set of hard particles serves a similar purpose but possesses an even greater level of hardness, thereby improving the overall performance of the valve seat.
The second patent further elaborates on a valve seat constructed from an iron-based sintered alloy, intended for installation in the cylinder head of internal combustion engines. This innovative structure features a double-layer design formed through a sintering process, which enhances durability and performance. The valve-seating and head-seating sections are differentiated by their specific porosities and densities, allowing for a considerable level of customization in performance attributes. Additionally, solid lubricant particles may be incorporated into the base matrix to enhance functionality.
