Fabrication of porous stainless steel 316l for biomedical applications

Porous metals are very attractive materials for biomedical application as the physical and mechanical properties of these materials can be tailored similarly to the natural bone. In this work, porous stainless steel 316L has been fabricated by foam replication method. This method offers a lot of adv...

description Porous metals are very attractive materials for biomedical application as the physical and mechanical properties of these materials can be tailored similarly to the natural bone. In this work, porous stainless steel 316L has been fabricated by foam replication method. This method offers a lot of advantages including of easy processing technique, very economic, does not involve the use of toxic chemical and capable of producing porous structure that almost similar to natural bone. The porous stainless steel 316L (SS316L) samples were prepared by varying the SS316L composition from 40 wt% to 60 wt%. Sintering process was carried out at 1250°C in a vacuum furnace.
