Abstract: A method of joining a plurality of parts to form a unitary body includes the step of providing at least two sintered parts, each of the parts being formed of carbide or cermet, and: at least one of the parts having at least one inner cavity. The at least two sintered parts can be assembled into a shape of a unitary body, wherein each of the at least two parts has a joining surface and when each joining surface is brought into contact, the joined surfaces form a bonding interface therebetween. The assembled parts are subjected to a vacuum or gas atmosphere, without the application of external pressure, and to a temperature sufficient to fuse the at least two sintered parts together at the bonding interface to form the unitary body.

Abstract: A method of joining a plurality of parts to form a unitary body includes the steps of providing at least two sintered parts, each of the parts being formed of a cemented carbide or cermet, at least one of the sintered parts having at least one internal channel. The at least two sintered parts are assembled into a shape of a unitary body, wherein each of the at least two parts has a joining surface and when each joining surface is brought into contact the joined surfaces form a bonding interface therebetween. The assembled at least two parts are subjected to a vacuum or gas atmosphere, without the application of external pressure, and to a temperature sufficient to fuse the at least two sintered parts together at the bonding interface to form the unitary body.
