From these GDOES signals, it is possible to find out three sublayers.
To find out all the sublayers, based on Figure 4, the derivatives by sputtering time of the GDOES signals were calculated and are presented in Figure 5, for phosphorus, copper, oxygen, nitrogen, tantalum, and calcium along with their derivatives, respectively.
Chemical analysis of the anodic oxide layer was conducted using GDOES (Figure 11).
(4) GDOES shows the presence of Mg and Al elements suggesting the oxidation of the substrate and the formation of [Mg.sup.2+] and [Al.sup.3+] ions.
The top surface analysis of the samples was studied by glow discharge optical emission spectroscopy (GDOES)  using a GD Profiler 2 from Horiba/Jobin Yvon.
The elemental composition of the films was examined by both X-EDS and GDOES. The texture of the Ag:HAp films deposited with [x.sub.Ag] = 0 and [x.sub.Ag] = 0.5 after the heat treatments at 600[degrees]C (Figure 1) has been determined by SEM.
These samples were only used for measuring chemical profiles by glow discharge optical emission spectrometry (GDOES) tests.
GDOES (Horiba Jobin-Yvon RF Profilometer) was used to evaluate the semi-quantitative composition and thickness of the ALD deposits.
Depth profiles in graphs, valuated by GDOES
, show steady transition of chemical composition from coating to base material.
Glow discharge optical emission spectrometry (GDOES) was performed using a Horiba Jobin-Yvonne GD-Profiler to determine the thickness and the in-depth composition of the ALD coatings.
The GDOES profiles of the sample B were selected to be shown in Fig.
In addition, the chemical element distribution in the conversion film and its morphology were investigated by glow discharge optical spectroscopy (GDOES
) and conventional scanning electron microscopy (SEM).
