China's powder metallurgy products industry in the middle of 50s, after the start, with the development of the automotive industry, with its own characteristics of the section, the growing attention. At present, the production of powder metallurgy parts in China has entered a period of high speed development.
But in recent years, due to the rise of some new technologies, such as mechanical alloying, metal powder injection molding, warm compaction, spray forming, microwave sintering, spark plasma sintering and self propagating high-temperature synthesis and sinter hardening, the powder metallurgy materials and technology has been paid more attention, its application has been more widely.
At present, powder metallurgy technology in China is developing in the direction of high density, high performance, integration and low cost. In recent years, a series of new powder metallurgy forming technology emerge in an endless stream, and showed accelerated development trend, metal injection molding, warm compaction, warm flow compaction, spray forming, high speed pressing forming technology are emerging, the powder of high density forming got great development.
