(4) can be produced can not be produced by ordinary melting method has a special structure and properties of materials and products, such as the new porous biomaterials, porous membrane materials, high-performance structural ceramics and functional ceramic materials. Using powder metallurgy method, can be refractory metals and their compounds, fake alloy, porous approach to manufacturing.
Powder metallurgy method can be suppressed as the ultimate size of the compacts, without demand or less demand for subsequent machining, silicon powder it can greatly thrifty metal, the product of capital down. (3) can easily achieve a variety of types of complex, give full play to the characteristics of each group element material is a low-cost production of high performance metal matrix and ceramic composite materials technology. The use made of porous powder metallurgy technology can, semi-compact or full-dense material and products, such as oil bearings, gears, cams, guides, tools, etc. (5) can achieve near net shape forming and automated mass production, and thus, can effectively reduce the production of resources and energy consumption. Manufacturing powder metallurgy products way, the metal consumption as long as 1-5%, and produced with ordinary casting method, the metal consumption may reach 80%.
(1) powder metallurgy technology can minimize the segregation of alloy components, eliminating bulky, uneven casting organization. (6) can take advantage of the ore, tailings, steel sludge, mill scale iron and steel, recycling scrap metal as raw material, a material can be recycled and effective utilization of new technologies.
Powder has a unique chemical composition and mechanical, physical properties, and these properties with the traditional casting methods can not be obtained. (2) can be prepared amorphous, microcrystalline, quasicrystals, nanocrystalline supersaturated solid solution and a series of Powder Coating System high performance non-equilibrium materials, these materials have excellent electrical, magnetic, optical and mechanical properties. Powder metallurgy materials produced in the melting process is not really material, also not afraid to mix oxygen from the crucible and the agent to bring impurities, and sintered in vacuum and restore normal held in an atmosphere without fear of oxidation, material does not give any pollution, therefore, or production of high purity materials. Powder suitable for producing uniform shape and quantity of the product, especially high gear and other products of processing, manufacturing powder metallurgy method can greatly decrease the cost of production.Production of ceramics and powder metallurgy method is somewhat similar, therefore, a series of powder metallurgy technology can also be used for the preparation of ceramic materials.) has an important role., is a small non-cutting process. In the preparation of high-performance rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high temperature superconducting materials, new metallic materials (such as Al-Li alloy, heat-resistant Al alloys, super alloys, manganese powder corrosion resistant stainless steel powder, powder high-speed steel, intermetallic compounds, high temperature structural materials, etc. As the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials, new materials development plays an important role
