Abstract
In order to develop a new ELID grinding system as a surface fabrication process for metallic biomaterials such as a Ti-6Al-4V alloy, ground surfaces were analyzed by using a TEM, XPS and a Nano-Hardness Tester (NHT). Chemical stability was examined by electrochemical corrosion tests using a three-electrode electrochemical cell connected to a computer driven potentiostat. In order to investigate the tribological properties, reciprocating sliding friction tests were also carried out. Finished surfaces produced by the new ELID grinding system showed higher corrosion resistance and tribological properties as compared to those of the polished surfaces. It is believed that this new system improves corrosion resistance and tribological properties by creating a thick oxide layer with a diffused oxygen and carbon element.
