Powder metallurgy is a technology to produce metal powder or use metal powder (or mixture of metal powder and non-metal powder) as raw material, through forming and sintering, to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to ceramic production, both belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials.
Powder metallurgy includes powder making and products. Among them, milling is mainly a metallurgical process, which coincides with the literal. Powder metallurgy products are often far beyond the scope of materials and metallurgy, often interdisciplinary (materials and metallurgy, machinery and mechanics, etc.) technology. In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science and laser technology, which makes powder metallurgy product technology become a modern comprehensive technology across more disciplines.
application area
Powder metallurgy related enterprises are mainly applied to the production and research of spare parts in the automobile industry, equipment manufacturing industry, metal industry, aerospace, military industry, instruments, hardware tools, electronic appliances and other fields, as well as the production of related raw materials and auxiliary materials, and the manufacturing of various powder preparation equipment and sintering equipment. Products include bearings, gears, carbide tools, molds, friction products and so on. In military enterprises, heavy weapons and equipment such as armor piercing projectiles, torpedoes, aircraft tanks and other brake pairs need to be produced by powder metallurgy technology. In recent years, powder metallurgy automobile parts have become the largest market in China's powder metallurgy industry, and about 50% of automobile parts are powder metallurgy parts.
