The intriguing Ti metal has excellent
biocompatible, superior mechanical properties and better resistance to corrosion. The aim at making titanium bioactive is pursuited. In this study, simple electrochemical treatment method was used to perform surface modification of Ti, followed by chitosan grafting via silane coupling. SEM, thin film XRD, and FTIR were used to characterize the treated Ti metals, tensile test and OCP for chitosan-grafted samples. Experimental results indicated the appearance of the anatase phase on electrochemically treated surface. Morghology was changed to much smooth structure after chitosan grafting to APTS. Moreover, the OCP of chitosan-grafting titanium samples shifted towards a steady state. anodic
