The aim of the present thesis work is the fabrication (by Pulsed Laser Deposition- PLD- and Magnetron Sputtering- MS) and the characterization of the mechanical properties of promising coating materials (Ti, Al2O3 and TiN) and structures (multilayers and functionally graded barriers) for high temperature operation of steels in heavy liquid metals. The mechanical properties are assessed by combining the outcome of nanoindentation and Brillouin spectroscopy measurements.
L'obiettivo di questo lavoro di tesi è la fabbricazione (da Pulsed Laser Deposition -PLD- e Magnetron Sputtering -MS) e caratterizzazione delle proprietà meccaniche di promettenti materiali per coating (Ti, Al2O3 e TiN) e architetture più avanzate (multilayers e functionally graded barriers) per acciai che operano ad alte temperature in metalli liquidi pesanti. La caratterizzazione è fatta incrociando i risultati di test di nanoindentazione e misure di spettroscopia Brillouin.

Abstract
The aim of the present thesis work is the fabrication (by Pulsed Laser Deposition- PLD- and Magnetron Sputtering- MS) and the characterization of the mechanical properties of promising coating materials (Ti, Al2O3 and TiN) and structures (multilayers and functionally graded barriers) for high temperature operation of steels in heavy liquid metals. The mechanical properties are assessed by combining the outcome of nanoindentation and Brillouin spectroscopy measurements.| File | Dimensione | Formato | |
