Abstract (EN): In this work an investigation of long period fiber gratings (LPFGs) over coated with iron (Fe) thin layers with different thicknesses and subjected to oxidation in air atmosphere under controlled temperature is presented. The formation of iron oxides was monitored in real time by following the optical features of the LPFG attenuation band. The morphology of the oxide layer was further analyzed by scanning electron microscope (SEM). Preliminary results show that iron coated LPFGs can be used as sensors for early warning of corrosion in projects where metal structures made of iron alloys are in contact with atmospheric air.
