In ultrasonic testing of thermally sprayed coatings difficulties often occur, which relate partly
to poor lateral and axial resolution, partly to the coarse grained structure of the coatings, and …

Thermally sprayed coating are usually tested destructively, ie metallo-graphically or by
applying various strength tests. In most cases the results of non-destructive testing NDT …

[en] For the nondestructive testing of coatings and thin walled components a combined test
procedure is presented, where ultrasonic pulses are sent into the component under test and …

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 …

The laser‐ultrasonic technique uses lasers to generate and detect ultrasound and present
interesting possibilities for characterizing thermal spray coatings in a non‐destructive …

Thermally sprayed ceramic coatings are widely used in industrial applications where the
coated component is subject to, eg high thermal loads or mechanical wear. The mechanical …

Thermal spraying of protective coatings has been in use since 1917 when the initial
application was the spraying of zinc layers onto steel structures to prevent corrosion [1]. In …

The non-destructive characterization of thermal spray coatings for thermal barriers, anti-wear
or anticorrosion coatings is of particular importance for quality control, but it can be also very …

The steadily increasing requirements to the properties of thermal spray coatings have to
lead to the development of new characterization tools, in particular for non-destructive …

Laser ultrasonics has come of age in such diverse industrial applications as in-process
evaluation during steel processing [1] and composite air frame inspection [2, 3]. This …
