in order to create high bone compatibility surface, a new ELID grinding system, in which a direct current of extremely short pulses are applied to the sample being ground was developed. After the titanium metal was subjected to a new ELID grinding, thin film Energy Dispersive X-ray Spectroscopy (EDS), X-ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscopy (SEM) results showed the titanium metal surfaces were covered by porous titania. In simulated body fluid (SBF), the titanium modified by a new ELID grinding system could induce apatite formation on its surface. Above results suggest that this newly developed ELID grinding system can facilitate rapid bone formation around the implant, reducing therewith the patient's recovery time after surgery.
