NONDESTRUCTIVE METHOD TO EVALUATE MICROSTRUCTURE OF SEGMENTED COATINGS

By applying a dye (10) to a segmented TBC (7) the penetrant remains between the columns (12', 12'',...) so that the microstructure of the segmented TBC (7) can be easily evaluated. En appliquant un colorant (10) sur un revêtement de barrière thermique segmenté (7), l'agent pénétr...
