The highly reflective Ag-based thin-film coating for the ITER optical diagnostic mirror was tested under annealing at 250-310 oC and steam exposure. The Ag grain growth triggered by elevated temperature was identified as the main reason for the deterioration of the coating reflectivity and structure. The SiNx/(SiOx/SiN_x)2 nanolaminate barrier composition over the Ag layer was found to effectively suppress the corrosive effect of steam. Keywords: surface degradation, silver mirrors, annealing, corrosion.
