This paper examines the tensile method for finding the adhesion property of plasma-sprayed coatings. The inadequacies of this method are clarified and a fracture mechanics approach is proposed. In this manner the variation in tensile strength for any set of samples may be ascribed to pre-existing defects within the coating.
