Summary of New Technology of Powder Metallurgy Forming in my country in the Past Ten Years

However, it has been successfully applied in the production of some complex-shaped Powder Metallurgy Parts. For example, a research team in China has used WFC technology to successfully produce a turbine impeller with complex curved blades, which has achieved a high density of 7.2g/cm3 and excellent mechanical properties. In addition, WFC technology has also been used to produce parts with complex internal structures, such as gears with internal splines and internal helical gears. These achievements indicate that WFC technology has great potential in the field of Powder Metallurgy and can greatly expand the application range of powder metallurgy parts.

3. Additive manufacturing technology

Additive manufacturing, also known as 3D printing, is a revolutionary technology that has gained significant attention in recent years. It allows for the direct production of complex-shaped parts layer by layer, without the need for traditional machining processes. In the field of powder metallurgy, additive manufacturing technology has been widely used to produce parts with complex geometries and customized designs.

There are several types of additive manufacturing technologies that can be used for powder metallurgy, including selective laser sintering (SLS), selective laser melting (SLM), and electron beam melting (EBM). These technologies use a laser or electron beam to selectively melt or sinter metal powders, layer by layer, to form the desired parts.

Additive manufacturing technology offers several advantages for powder metallurgy parts production. Firstly, it allows for the production of parts with complex geometries that are difficult or impossible to achieve with traditional manufacturing methods. Secondly, it enables the production of customized parts with specific designs and properties. Thirdly, it reduces material waste and improves material utilization, as only the required amount of powder is used for each part. Lastly, it offers the potential for on-demand production, reducing lead times and inventory costs.

In conclusion, the development of new forming technologies in powder metallurgy has greatly expanded the capabilities and applications of this advanced manufacturing technology. Temperature and pressure technology, flow temperature and pressure technology, and additive manufacturing technology have all contributed to the production of high-density, high-performance, and low-cost powder metallurgy parts. These advancements have further solidified the irreplaceable position and role of powder metallurgy in the material and part manufacturing industry.
