Abstract Scope |
Corrosion-related degradation of metallic components presents economic, safety and environmental issues in high-tech industries. In a circular economy approach, it would be relevant to propose new eco-designed solutions for extending the service life of metallic parts. The proposed method consists in incorporating luminescent particles into metallic parts by additive manufacturing in order to track their corrosion rate, using photoluminescence to monitor the materials degradation. In this study, laser powder bed fusion was used to successfully incorporate for the first time Ce3+ doped yttrium aluminum garnet (YAG:Ce) into a 316L stainless steel matrix by controlling the influence of process parameters. Chemical compositions and microstructural changes related to phosphors incorporation have been observed by energy dispersive spectroscopy (EDS) and backscatter diffraction (EBSD) respectively. Laser induced photoluminescence spectra of embedded particles revealed new optical features. Finally, preliminary tests in nitric environment have been carried out to monitor the corrosion rate of 316L. |
