In present work, an approach to porous PEO coating sub-layers determination on the basis of Glow-Discharge Optical Emission Spectroscopy (GDOES) measurements, is presented. CP Titanium Grade 2 was used for the study. By interpreting the depth profiles obtained by GDOES, the Authors could reveal boundaries of zones with specific features in the obtained coating. This way the porous PEO coating can be divided into different sub-layers. The use of the first and second derivatives of hydrogen, phosphorus and titanium signals in the GD profiles allowed to determine these sub-layers, with results shown in that article.
