Abstract
A method of obtaining a porous titanium surface suitable for medical implants is provided. The titanium surface is exposed to a plasma comprising a reactive plasma gas, the reactive plasma gas comprising an active etching species and a sputtering gas. The plasma conditions are effective to modify the titanium surface and provide surface porosity. The plasma conditions are effective to non-uniformly etch and sputter the titanium surface.
