METHOD OF JOINING SINTERED PARTS OF DIFFERENT SIZES AND SHAPES |
摘要 |
A method of joining a plurality of parts to form a unitary body. At least two sintered parts are provided. At least one of the sintered parts has at least one internal cavity. Each of the parts is formed of a hard metal composition of material. The at least two sintered parts are assembled into the shape of a unitary body. Each of the at least two sintered parts has a joining surface and when each joining surface is brought into contact the 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. |
