Such as pressure processing, improving the work density and size shape accuracy; the iron-based powder metallurgy parts quenching, surface hardening treatment can improve its mechanical properties; in order to reach lubrication or corrosion DHA resistance for purposes of oil or other liquid lubricant impregnated; low melting point metal infiltration pore in parts to infiltration processing, can be improving the work strength, hardness, plasticity and impact toughness.

 The advantages of powder metallurgy technology, 1, the vast majority of refractory metals and their compounds, pseudo alloy, porous materials can only be manufactured by powder metallurgy method. The parts after being sintered, there are still some tiny pores, which belongs to the porous material. Sometimes in order to reduce the pressure and increase parts density, also can use hot isostatic pressing method. Use powder metallurgy manufacturing methods, metal loss is only 1-5%, while using the general method of production, casting, metal loss can reach 80%. In addition, in powder metallurgy materials usually use manganese powder as the main material or additive, it can help to improve the properties of materials and the development of new materials.

Powder metallurgy is a technology used for producing metal powder, forming and sintering metal powder ( or metal powder and metal powder mixtures) made of materials and products. 4, powder metallurgy method can ensure the accuracy and uniformity of materials. Preparation of powder after sieving and mixing, uniform mixing and adding plasticizer, then pressing, atoms in powder through solid phase diffusion and mechanical lock effect make the parts are combined into a certain strength of the whole. 2, the powder metallurgy method can be pressed into the final size of the blank, but need not or rarely required subsequent machining, so it can greatly save metal, reduce the غير مجاز مي باشدt of product. 3, the powder metallurgy technology in material production process is not melting materials, and is not afraid of mixing with the crucible and the impurities deoxy agent, and sintering is generally in a vacuum and restore atmosphere, is not afraid of being oxidized, and will not bring any pollution to material, so it is possible to produce high purity materials.mhcmp. Due to different kinds of atomic diffusion under the high temperature, oxide powder surface by reduction and recrystallization of deformation of powder, the powder particles are combined with each other, improve the strength of powder metallurgy products, and get similar organizations with the general alloy.
