What are the characteristics of cemented carbide powder metallurgy?


  cemented carbide powder metallurgyIt is a process method for making metal powder or metal powder (or a mixture of metal powder and non-metal powder) as raw materials, after molding and sintering, to make metal, composite and various types of articles. Powder metallurgy method and ceramics have similarities, all belong to the powder sintering method, so a series of new methods of powder metallurgy can also be used for the production of ceramics. Due to the advantages of powder metallurgy methods, it has become the key to solving new problems and plays an important role in new developments.


Cemented carbide powder metallurgy contains powders and articles. The powder is mainly a metallurgical process, which is literally consistent. Powder metallurgy items are often far beyond the scope and metallurgy, beyond the multidisciplinary (and metallurgical, mechanical and mechanical, etc.) approach. Especially the modern metal powder 3D printing will mechanical engineering, CAD, reverse engineering methods, layered production method, numerical control method, scientific, laser way integration, the powder metallurgy goods way to become a modern comprehensive approach across more disciplines.


What are the characteristics of cemented carbide powder metallurgy?


Cemented carbide powder metallurgy has unique chemical composition and mechanical and physical properties, which can not be obtained by traditional casting methods. The use of powder metallurgy methods, you can directly produce porous, semi-density or fully dense and items (such as planetary bearings, gears, cams, rails, tools, etc.), is the way to cut less.

(1) hard alloy powder metallurgy method can effectively reduce the bias of the alloy composition, eliminate the coarse uneven casting organization. It plays an important role in the preparation of high performance rare earth permanent magnet, rare earth hydrogen storage, rare earth luminescence, rare earth catalyst, high temperature superconductivity, new metals (such as Al-Li alloy, heat resistant Al alloy, high temperature alloy, powder corrosion resistant stainless steel, powder high speed steel, intermetallic compound high temperature structure, etc.).


(2) A series of high-performance imbalances with excellent electrical, magnetic, optical and mechanical properties such as amorphous, microcrystalline, quasicrystalline, nanocrystalline, and supersaturated solid solutions can be prepared.


(3) Cemented carbide powder metallurgy can easily achieve a variety of types of composite, give full play to the original characteristics of each group, is a low-cost high-performance metal machine and ceramic composite process.


(4) cemented carbide powder metallurgy can be new porous biological, porous separation membrane, high-performance structural ceramic abrasive, functional ceramics and other ordinary smelting methods can not have special structure and performance and articles.


(5) can be almost smoothly formed and a large number of automation, effectively reducing the consumption of resources and energy.


(6) ore, tailings, steelmaking sludge, rolling iron scale, scrap metal can be recycled as raw materials of the new approach.


Most of our common processing tools and hardware grinding machines arecemented carbide powder metallurgymethod of production.
