Latest Patents
One of Hakakoshi's latest patents is a method of manufacturing a clad material of bronze alloy and steel. This method involves scattering a bronze alloy powder on a steel back metal and sintering it to create a bilayer material. The process ensures that the bronze alloy layer maintains a porosity of 3% or less, allowing for efficient heat treatment without the formation of new voids. This innovation enhances production efficiency by enabling a high-density bronze alloy layer with reduced rolling times.
Another notable patent is for a composite sliding member with a high porosity sintering layer. This design suppresses the exposure of a porous metal layer, enhancing anti-seizing properties while maintaining rear resistance. The composite slide member consists of a back plate and a slide layer that includes a porous metal layer with a porosity of 50% to 80%. The porous metal layer is formed by sintering metal powder without applying pressure, resulting in a unique structure that improves performance.
