Powder metallurgy is the preparation of metal powder or a metal powder (or mixture of metal powder and nonmetal powder) as the starting material, after forming and sintering, metal materials, composite materials and various types of technology products. Powder metallurgy and production of ceramics have similarities, belong to the powder sintering technique, therefore, a series of powder metallurgy new technology also can be used for preparation of ceramic materials. Because of the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials, plays an important role in the development of new materials.
Including milling and powder metallurgy products. Wherein the flour is mainly metallurgical processes, and literally fit. And powder metallurgy products are often far beyond the material and metallurgy, often across multiple disciplines (materials and metallurgy, machinery and mechanical, etc.) technology. In particular, modern metal powder 3D printing [1-2], a mechanical engineering, CAD, reverse engineering, layered manufacturing technology, numerical control technology, materials science, laser technology in one, making powder metallurgy products technology become more modern cross-disciplinary integrated technology.
