Advanced powder forging and sintering technologies of components manufacturing

摘要

After the development of an advanced Powder Metallurgy routes, new powder materials and composites are now essential components in many fields of technology, because of their ability to provide desired mechanical and other physical properties. The analysis of current status and choice of main directions of PM technologies development is presented in this review. In the industry of sintered PM components, the total amount of production is being increased and their dominant application is being disseminated. In particular, their use for the various most attractive applications is analysed, and innovative technology options are developed by Metal Forming Institute (INOP) and implemented in industry. Some PM high density forging, warm flow compaction, SPS and PASHS technologies developed by INOP are discussed. Advanced powder forging and sintering technologies developed in INOP are fallowings: I) powder forging technology of high dense components; II) solid lubrication technologies of PM components; III) warm flow compaction/forging technology of complex shape PM components; IV) debinding-sintering technology of warm formed components; V) reaction sintering technologies of steel based components; VI) spark plasma sintering technology of new nano-structured composites; VII) pressure assisted SHS synthesis technology. Some of the main results of the listed technologies are shown in the paper.
