What are the requirements of powder metallurgy technology?

Powder metallurgy technology can easily realize multiple types of composite, give full play to the characteristics of each element of the respective materials, is a technology for the production of high performance metal matrix and ceramic composite materials with low cost. So what are the requirements of powder metallurgy technology?

1, powder metallurgy technology can minimize the alloy composition segregation, eliminating coarse and uneven casting organization.

2, powder metallurgy technology can be prepared in amorphous and microcrystalline, crystal, nano crystal and super saturated solid solution and a series of high performance non equilibrium materials. These materials have excellent electrical, magnetic, optical and mechanical properties.

3, powder metallurgy technology can realize the near net shape forming and automatic batch production, which can effectively reduce the production of resources and energy consumption.

4, powder metallurgy technology can produce ordinary smelting method can produce with special structure and properties of materials and products, such as a new type of porous biomaterials, porous separation membrane materials, high performance structure ceramic abrasive and ceramic materials and other.

5, powder metallurgy technology can make full use of ore, tailings, steelmaking sludge, steel rolling mill scale, recycling of scrap metal as raw materials, is a kind of new technology can effectively carry out the material recycling and comprehensive utilization.

Powder metallurgy metal has a unique chemical composition and mechanical and physical properties, and these properties is conventionally casting method can not be obtained. The powder metallurgy technology can be directly made into porous, semi dense or fully dense materials and products, such as oil bearing, gear, cam, guide rod, cutter, etc.
