Nowadays, the porous coatings enriched in determined chemical elements on CP Titanium Grade 2 may be obtained by Plasma Electrolytic Oxidation (PEO), the process also known as Micro Arc Oxidation (MAO). It should be pointed out that DC, AC, or pulse voltage may be used to create these coatings; however, their structures, chemical composition and mechanical properties are always different than the substructure (matrix). It should be also noted that they may be used in a wide range of applications, such as biomaterials, catalysts, sensors as well as wear resistant coatings. In this paper, the fabrication and characterization of PEO coatings obtained on CP Titanium Grade 2, which are porous and enriched in biologically active chemical elements, are presented.Keywords: Plasma electrolytic oxidation, porous coatings, DC PEO, CP Titanium Grade 2
