Abstract

To clarify the effects of the ELID (Electrolytic In-process Dressing) grinding on surface characteristics of the biomaterial Ti-6Al-4V alloy, electrochemical corrosion tests were carried out using a three-electrode electrochemical cell connected to a computer driven potentiostat. The processed surfaces were analyzed by the X-ray Photoelectron Spectroscopy (XPS). The surface hardness of the samples was measured by a Nano Hardness Tester (NHT). The surface finished by the ELID grinding method showed higher corrosion resistance, compared to the surface finished by polishing. This is due to the influence of the oxidized layer on the surface and also due to the diffusion of oxygen. The diffused oxygen accelerates the regeneration of the oxide layer broken by the raised potential and prevents the dissolution of metal ions. Surface hardness was increased by the ELID grinding. This is because of the existence of the carbon diffused layer beneath the surface.
