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 …

The integrity, and especially, the cohesive strength of alumina plasma-sprayed coatings
prepared from a range of precursor powders of different size and crystallinity has been …

A round-robin test was implemented where nine European research institutions and
universities applied different thermal, ultrasonic and magnetic methods for measuring the …

Post-fabrication cool down (secondary cooling) is said to be the major cause of the residual
stress in thermally sprayed coatings. Primary cooling, the cooling of spray particles to …

The adhesion strength of plasma-sprayed coatings to a substrate is an often-used but poorly-
understood term. The methods of determining the adhesion strength are quite simple and …

Presently, no satisfactory method for measuring the coating–substrate adherence in plasma‐
sprayed ceramic–metal systems exists. Conventional pull‐off methods must rely upon …

The technique of spray coating is an effective means of providing individual components
with specific properties (heat resistance, corrosion resistance, wear resistance, etc) by …

A round-robin test was implemented where nine European research institutions and
universities applied different thermal, ultrasonic, and magnetic methods for measuring the …

In thermal spraying processes, residual stresses mainly arise from two sources:(i) shrinkage
of the sprayed particles after solidification (primary cooling process) and (ii) differences …

There is typically a large scatter in the observed failure stress, particularly for ceramic
coatings. Failure can thus occur not only at the coating-substrate interface where it is desired …
