Abstract: Pure titanium samples were obtained using electrical discharge machining (EDM) on a spark erosion machine. Twenty-two titanium samples were obtained exhibiting a wide range of arithmetic roughness (R_a) varying from 1 to more than 20.9 µm. The surfaces present an isotropic structure formed by successive peaks and valleys. No specific direction or periodical structure is visible on surfaces. It is shown that the surfaces present similar morphological structures since the surfaces appear like a zoom of the surface at a lower grade while the grade rises. It is shown that it exists a bandwidth in the amplitude roughness where surfaces lost significantly their biocompatibility. However, electro-erosion is an appropriate tool-machining process to increase the biocompatibility of titanium implants when creating a relevant roughness.
