POWDER NETALLURGICAL PRODUCTION OF A COMPONENT HAVING POROUS AND NON POROUS PARTS

摘要

present invention is manufactured or processed by powder metallurgy to the components and the production of this type of component is related to the process . The components are manufactured by the powder metallurgy while having a porous zone fluid- sealing properties , and to provide , also to be possible to properly manufacture flexible with less corresponding to those components . For this purpose , this type of component has at least one porous zone formed from a solid solution or an intermetallic phase . However, also this type of component may also have a surface coating appropriate . Moreover , this type of component has at least one local fluid formed from a metal or a metal -to- phase or a solid solution of the metal alloy present in the sealed zone .
