Title: Noriaki Chida: Innovator in Piston Ring Technology
Introduction
Noriaki Chida is a prominent inventor based in Ichinoseki, Japan. He has made significant contributions to the field of piston ring technology, holding two patents that enhance the performance and durability of internal combustion engines. His innovative approaches focus on reducing friction and improving toughness in sliding members.
Latest Patents
Chida's latest patents include a sliding member designed to provide low friction and excellent toughness. This sliding member, such as a piston ring, is coated with a Cr-B-Ti-V-(Mn, Mo)-N-based alloy film on its sliding surface. The alloy film contains one or both of manganese (Mn) and molybdenum (Mo) with a total content of 2 mass % or less. Additionally, the composition of the alloy film is carefully controlled, with boron (B) content ranging from 0.1 mass % to 1.5 mass %, vanadium (V) content from 0.05 mass % to 1 mass %, and titanium (Ti) content from 0.05 mass % to 1.5 mass %.
Another notable patent is for a piston ring that features a sliding surface covered with a Cr-B-V-N alloy film. This piston ring achieves higher wear resistance, cracking resistance, and peeling resistance. The B content in this alloy film is maintained within a range of 0.1-1.5 mass %, while the V content is kept between 0.05-1 mass %. The ratio of B content to V content is also optimized to be greater than 1 and 30 or less. This innovative piston ring is particularly suited for engines that utilize alcohol fuel or alcohol-containing fuel.
