Powder metallurgy is an industrial technology for producing metal powders or using metal powders (or mixtures of metal and non-metal powders) as raw materials, forming and sintering them to produce metal materials, composite materials, and various types of products. Powder metallurgy technology has been widely applied in fields such as transportation, machinery, electronics, aerospace, weapons, biology, new energy, information, and nuclear industry, becoming one of the most dynamic branches of new materials science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product accuracy, and good stability, making it very suitable for large-scale production. In addition, some materials and complex parts that cannot be prepared by traditional casting and mechanical processing methods can also be manufactured using powder metallurgy technology, which has attracted much attention from the industry.
The broad powder metallurgy products industry includes iron and stone cutting tools, hard alloys, magnetic materials, and powder metallurgy products. The narrow definition of powder metallurgy products industry only refers to powder metallurgy products, including powder metallurgy parts (accounting for the vast majority), oil containing bearings, and metal injection molded products.
Characteristic:
Powder metallurgy has unique chemical composition and mechanical and physical properties that cannot be obtained by traditional casting methods. The use of powder metallurgy technology can directly produce porous, semi dense or fully dense materials and products, such as oil containing bearings, gears, camshafts, guide rods, cutting tools, etc., which is a minimal cutting process.
(1) Powder metallurgy technology can minimize the segregation of alloy components and eliminate coarse and uneven casting structures. It plays an important role 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, and new metal materials (such as Al Li alloys, heat-resistant Al alloys, superalloys, powder corrosion-resistant stainless steel, powder high-speed steel, intermetallic compound high-temperature structural materials, etc.).
(2) A series of high-performance non-equilibrium materials can be prepared, including amorphous, microcrystalline, quasicrystalline, nanocrystalline, and supersaturated solid solutions, which have excellent electrical, magnetic, optical, and mechanical properties.
(3) It is a low-cost process technology for producing high-performance metal based and ceramic composite materials that can easily achieve various types of composites and fully utilize the characteristics of each component material.
(4) It can produce materials and products with special structures and properties that cannot be produced by ordinary melting methods, such as new porous biomaterials, porous separation membrane materials, high-performance structural ceramic grinding tools, and functional ceramic materials.
(5) It can achieve near net formation and automated mass production, thereby effectively reducing resource and energy consumption in production.
(6) It is a new technology that can effectively carry out material regeneration and comprehensive utilization by fully utilizing ores, tailings, steelmaking sludge, steel rolling scales, and recycled scrap metals as raw materials.
Many of the commonly used machining tools and hardware grinding tools are manufactured using powder metallurgy technology.
Main Products
Advanced equipment for powder metallurgy research - Spark Plasma Sintering System (SPS)
With the development of high-tech industries, the types and demand for new materials, especially new functional materials, are constantly increasing. The new functions of materials call for new preparation technologies. Spark Plasma Sintering (SPS) is a new technology for preparing functional materials, which has distinct characteristics such as fast heating rate, short sintering time, controllable microstructure, energy saving and environmental protection. It can be used to prepare metal materials, ceramic materials, composite materials, as well as nano block materials, amorphous block materials, gradient materials, etc.
