In this study, a new laser based technique was evaluated for the characterization of plasma-
sprayed oxide coatings. It uses the contactless laser generation and detection of ultrasonic …

A test method has been developed which allows the determination of the shear stress
necessary to cause adhesive or cohesive failure of plasma-sprayed coatings. The shear …

In order to properly characterize the entire deposition process, evaluation of the coating,
including a reliable metallographic preparation technique which reveals the true …

Ultrasonic methods are developed for characterizing plasma-sprayed coatings. First,
ultrasonic spectroscopy is used to determine the acoustic properties of various plasma …

Plasma-spray coatings are widely used in industry to protect the substrate against
aggressive environments or to alter the surface properties to enhance the wear resistance …

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 …

Failure in plasma-sprayed thermal barrier coatings systems mostly takes place in the
ceramic topcoat or at the interface between the topcoat and the bondcoat. The failure …

Coatings, as most industrial products, must be tested at the Research and Development
stage, in production environment, but it should be kept in mind that coating properties …
