Powder metallurgy accessories

Powder metallurgy is a process technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering, to produce metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics, and both belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problems of new materials and plays a pivotal role in the development of new materials.

Powder metallurgy includes milling and products. Among them, pulverization is mainly a metallurgical process, which is consistent with the literal. The powder metallurgy products often go far beyond the scope of materials and metallurgy, and are often cross-disciplinary (materials and metallurgy, machinery and mechanics, etc.) technology. Especially modern metal powder 3D printing, which integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, and laser technology, makes powder metallurgy products technology a modern comprehensive technology that spans more disciplines.

Powder metallurgy products, professional powder metallurgy

Powder metallurgy has unique chemical composition and mechanical and physical properties, and these properties cannot be obtained by traditional melting and casting methods. The use of powder metallurgy technology can directly produce porous, semi-dense or fully dense materials and products, such as oil-bearing bearings, gears, cams, guide rods, cutting tools, etc., which is a rare cutting process.

(1) Powder metallurgy technology can greatly reduce the segregation of alloy components and eliminate coarse and uneven casting structures. 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 metal materials (such as Al-Li alloys, heat-resistant Al alloys, super alloys, powder corrosion-resistant stainless steel, powder High-speed steel, intermetallic compounds, high-temperature structural materials, etc.) play an important role.

(2) A series of high-performance non-equilibrium materials such as amorphous, microcrystalline, quasicrystalline, nanocrystalline and supersaturated solid solution can be prepared. These materials have excellent electrical and magnetic properties. Academic, optical and mechanical properties.

(3) It can easily realize multiple types of composites and give full play to the characteristics of each component material. It is a low-cost production of high-performance metal matrix and ceramic composite materials. Technology.

(4) It can produce materials and products with special structures and properties that cannot be produced by ordinary smelting methods, such as new porous biological materials, porous separation membrane materials, and high-performance structural ceramic mills. Tools and functional ceramic materials, etc.

Many of our common machining tools and metal abrasive tools are manufactured by powder metallurgy technology.
