Abstract
In this experimental work, the effect of sol-gel TiO2 coating on adhesion energy of alumina scales formed on FeCrAl alloys was investigated. The adhesion energy was evaluated by means of a tensile test in the SEM chamber for the samples oxidized in air at 850 and 950°C during 72 h. In addition, the spallation rate of alumina scales was studied as a function of the imposed longitudinal strain.
