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

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

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 …

A basic requirement for a satisfactory plasma sprayed coating is that it should not be easily
detached from the substrate during use, a property which is usually rather loosely defined as …

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 …

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 morphological and surface chemical properties of plasma-sprayed coatings on metals
have been investigated using surface characterization techniques. Organic polymeric and …

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

The durability of plasma-sprayed metals bonded with a polyimide adhesive has been
studied. Metal adherend surfaces were prepared for adhesive bonding by plasma-spraying …

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 …
