New technologies expand the branches of powder metallurgy application

摘要

Powder metallurgy became the manufacturing technology in 1920s and remains the dynamical manufacturing branch that last develops now. In accordance with development rate (the annual rate of world production growth is on average about 10%) powder metallurgy outstrips the majority of production processes. The main driving force for development of this branch is fast growth of automotive manufacturing sector. It consumes about 70-80% of all-world powder metallurgy production. At the same time consuming amount of powder details and articles is increasing also in another manufacturing branches as electrical engineering, production of instrument etc. The object of this work that is fulfilled on the base of analysis of the last foreign date lies in demonstration by any examples that powder technologies don't stay the same but they are developing permanently. It is showed that increase of consumption amount of powder metallurgy production and expedition their application branches depend on new production technologies appearance to significant extent.
