POWDER METALLURGICAL PRODUCTION OF A COMPONENT HAVING POROUSAND NON POROUS PARTS

摘要

The invention relates to components which are produced or processed by powde r metallurgy, and to processes for producing components of this type. The components produced by powder metallurgy are intended both to have porous regions and to provide fluid-tight properties, and it should also be possibl e to produce them at correspondingly low cost and suitably flexibly. For this purpose, a component of this type has at least one porous region, which is formed from an intermetallic phase or solid solutions. However, it may also have a corresponding surface coating. Moreover, in a component of this type there is at least one areal fluid-tight region which is formed from a metal or metal alloy of the corresponding intermetallic phase or solid solution.
