Combined with the current situation of iron-based powder metallurgy technology and downstream development prospects in China and abroad, the future development direction of iron-based powder metallurgy mainly includes four categories.
To further improve the high consistency, high precision, complex shape and other characteristics of powder metallurgy, for machinery, automobile, home appliances and other industries to upgrade the industrial structure. This kind of direction is mainly oriented to reduce the weight of machinery, save energy consumption, reduce emissions and miniaturization of equipment, civilian-oriented.
Improve the density of iron-based powder metallurgy, improve the scope of powder metallurgy parts to replace traditional forgings. Currently, the density of mainstream iron-based powder metallurgy is 7.2-7.4g/cm3, while China's most technologically advanced Dongmu has already increased its density to 7.6g/cm3, at this density, iron-based powder metallurgy has replaced the majority of automobile, machinery and other connecting parts and part of the functional parts. In consideration of the powder metallurgy itself on the material savings and its own environmental characteristics, the theory of such iron-based powder metallurgy parts of the downstream space up to the level of hundreds of billions of dollars.
Improve the electromagnetic properties of powder metallurgy parts, the goal of silicon steel and ferrite and other materials to replace. Oriented silicon steel, for example, silicon steel conductive principle for the addition of silicon and other elements, through the reduction of grain boundaries and other ways to reduce iron loss - especially oriented silicon steel, in the direction of the guide that is a single coarse grain. Relative to the orientation of silicon steel, one-dimensional conductive direction, powder metallurgy parts can be realized in any direction of multi-dimensional conductive, that is, the formation of a product that is a single grain.
Further alloying, the goal of lightweight and functional. In the iron-based powder, mixed with aluminum, magnesium and rare earth elements and other alloy powders, can achieve its ultra-thin, lightweight and other properties, can be widely used in electronic equipment and wearable devices and other closely related to life in the field.
