The present study deals with information that could be obtained by real-time contactless
monitoring of the normal displacement, due to the propagation of the longitudinal waves …

The aim of the present study is to investigate a conventional laser-ultrasonics technique for
the determination of intrinsic properties of oxide coatings and their adhesion strength on a …

The aim of the present study is to investigate a laser-ultrasonic method to determine the
oxide-coating's adhesion strength on a metallic substrate. In order to demonstrate this …

The aim of the present study was to investigate the possibility of using a laser ultrasonic
technique for the estimation of the adhesion of ceramic coatings, deposited onto metallic …

A novel scheme for the measurement and characterization of the adhesion strength of solid
coatings on solid substrates is being presented. Although the method is presently restricted …

A numerical model is established to investigate the influence of transparent coating
thickness on the laser-generated thermoelastic force source and ultrasound waves in the …

Multichannel acoustic emission (AE) measurements by four laser interferometers were
developed and applied during a plasma-spray coating process that is known as being a …

A pulsed laser technique, based on conventional laser acoustics testing, has been
developed to define the spall resistance of sputtered oxide films on a metallic target. Direct …

Nondestructive methods previously developed for the detection of flaws, such as
delaminations, or for the evaluation of the elastic properties of materials, could be judiciously …

This paper presents a new and original model of laser ultrasonics, adapted to structures
made of two homogeneous and orthotropic layers (painted metals, composites, etc.). The …
