Powder metallurgy is producing metal powder or with metal powder (or the mixture of metal powder and nonmetal powder) as raw material, after forming and sintering, manufacturing metal materials, composite materials and processing technology of all kinds of products.The powder metallurgy method is similar to the production ceramics, which belongs to powder sintering technology. Therefore, a series of new powder metallurgy techniques can also be used for the preparation of ceramic materials.Due to the advantages of powder metallurgy technology, it has become the key to solve new material problems and plays an important role in the development of new materials.

Powder metallurgy includes powder and products.The powder is mainly the metallurgical process, and the literal coincidence.The powder metallurgy products often go far beyond materials and metallurgy, and are often interdisciplinary (materials and metallurgy, mechanics and mechanics, etc.).Especially modern metal powder 3 d printing, mechanical engineering, CAD and reverse engineering technology, layered manufacturing technology, numerical control technology, material science, laser technology, the technology of powder metallurgy products become more across disciplines of modern integrated technology.
