Tensile adhesion tests (TATs) which are normally utilized for industrial quality control
procedures have been used for research purposes to examine failure mechanisms of …

Techniques have been developed for measuring the tensile properties of plasmasprayed
coatings which are used in thermal barrier applications. The measurements have included …

Degradation in bond strength of plasma-sprayed thermal barrier coatings under thermal
cycling was evaluated by tensile adhesion tests. The bond strength and failure mode for two …

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 …

A plasma‐sprayed thermal barrier coating consisting of a NiCoCrAlY bond coat and Ce‐
stabilized zirconia ceramic coating was heat‐treated at 400° C for 1000 h. Microhardness …

In this work thermally induced failure processes of plasma-sprayed thermal barrier coatings
were examined. Cracking processes give rise to noise which was monitored by acoustic …

SUMMARY A fracture mechanics approach is applied to measuring the adhesion of plasma
and flame sprayed coatings of mild steel, nickel-aluminium composite and alumina applied …

The critical load for adhesion of 75% WC-Co+ 25% Ni alloy plasma sprayed coatings was
evaluated by an interfacial indentation test. A statistical analysis—piecewise linear …

The static and low cycle fatigue strength of an air plasma sprayed (APS) partially stabilized
zirconia thermal barrier coating (TBC) is experimentally evaluated. The shear testing utilized …

The structure of thermally sprayed coatings consists of lamellae which are oriented parallel
to the substrate surface. Coatings most often consist of a metallic bond coat and a ceramic …
