"Plasma-sprayed ceramic coatings contain a high density of intrasplat microcracks which are responsible for small Young\u017Ds moduli and low fracture toughness. The extension of an initial surface crack in the direction to the interface, where the crack is repelled by the metal substrate with higher Young\u017Ds modulus, is studied using the methods of fracture mechanics. It is shown that high tensile stresses induced by the crack in the interface can lead to a local decohesion along the interface so that the crack can deviate into the interface" .
