Abstract
A method for fabricating porous metal constructs (such as porous Ti constructs) which may be used as implants in bone repair is disclosed. The method employs a new saltbath sintering process coupled with conventional powder metallurgy technology which is capable of fabricating porous metal constructs with controlled porosity and pore size having a lower production cost than conventional powder metallurgy methods.
Claims20
A method for fabricating biocompatible porous metals, the method comprising:
- mixing a metal powder and a salt to form a mixture;
- compacting the mixture in a die under pressure to form a construct comprising a predetermined shape;
- and
- sintering the construct in a molten sodium chloride bath to produce a sintered construct.

A method for fabricating biocompatible porous titanium, the method comprising:
- mixing a titanium powder and a salt to form a mixture;
- compacting the mixture in a die under pressure to form a construct comprising a predetermined shape;
- sintering the construct in a molten sodium chloride bath to produce a sintered construct;
- and
- removing at least a portion of the salt from the sintered construct to reveal a plurality of pores defined through a portion of the sintered construct.
