EnglishIn this work three experimental glass compositions have been applied and tested on ferritic stainless steel (FSS) substrates with and without yttria-stabilized zirconia (YSZ) coating deposited by plasma spraying. Samples have been tested at 780°C in static air up to 1000 hours to investigate the materials compatibility, stability and interactions at the interfaces. Microstructural changes and migration of elements have been characterized postexperiment in cross-section by means of scanning electron microscopy and energy dispersive X-ray analysis. Two of the tested compositions resulted well adherent to the metal substrate for the whole test duration and the interface evolved with the formation of a stable Cr, Mn-rich layer due to the steel oxidation. The application of YSZ allowed all the glass composition to bond to the substrate and effectively act as a diffusion barrier limiting the diffusion of the substrate elements.

Samples have been tested at 780°C in static air up to 1000 hours to investigate the materials compatibility, stability and interactions at the interfaces. Microstructural changes and migration of elements have been characterized postexperiment in cross-section by means of scanning electron microscopy and energy dispersive X-ray analysis. Two of the tested compositions resulted well adherent to the metal substrate for the whole test duration and the interface evolved with the formation of a stable Cr, Mn-rich layer due to the steel oxidation. The application of YSZ allowed all the glass composition to bond to the substrate and effectively act as a diffusion barrier limiting the diffusion of the substrate elements. | |
