Nondestructive evaluation of bonding quality of dual-layer coatings based on the multi-feature ultrasonic method

•A multi-feature ultrasonic (MFU) method was proposed to evaluate the bonding condition of dual-layer coatings.•Parametric numerical studies were carried out to study the influence of stiffness at two interfaces on different ultrasonic features.•Stacked sparse autoencoder (SSAE) was applied to autom...
