In vitro corrosion study of porous metal fibre coatings for bone ingrowth.
As a first part of a biocompatibility testing programme, in vitro corrosion tests were carried out on porous stainless steel AISI 316L and titanium compacts made of 100 microns thick fibres. The present porous metal structures are used as coatings on permanent orthopaedic implants; with osseous tissue invading the pores, the implant becomes securely anchored to the surrounding bone. The results show that no inadvertent reactions occur with porous titanium. It can probably be used with no greater risk of localized electrochemical attack than the parent bulk material.
