Latest Patent Applications
Moronuki's notable patent application is titled "Combination of Cylinder Bore and Piston Ring." This application aims to provide a combination of a cylinder bore and a piston ring that exhibits excellent scuffing resistance and wear resistance with low friction loss, even under severe sliding conditions with a high load applied to an engine. The invention utilizes a thermal spraying technique on a cylinder bore, allowing the use of a standard die-cast aluminum alloy. A thermally sprayed iron-based coating is formed on the piston-ring-sliding surface of the cylinder bore, which has an Rpk of less than 0.20 μm in surface roughness. This is combined with a hard carbon coating on the outer peripheral sliding surface of the piston ring, which has an Rpk of less than 0.15 μm in surface roughness, specifically designed for internal combustion engines.
