From: Low voltage environmentally friendly plasma electrolytic oxidation process for titanium alloys
(a) XRD patterns of Ti-A and Ti-B. The patterns show that the addition of aminophenol to the bath chemistry has no influence on the crystallographic signature of the formed oxide layer. (b) Raman spectrum of Ti-A with peak deconvolution. (c) Raman spectrum of Ti-B with peak deconvolution. The amorphous carbon signature detected in the oxidized layer is due to the addition of aminophenol to the PEO bath. (d) List of functional groups associated with the Raman bands observed in deconvoluted SERS spectra.
