Description
  • Plazmově stříkané keramické povlaky obsahují uvnitř splatů vysokou hustotu mikroskopických trhlin, které jsou odpovědné za malé hodnoty Youngova modulu a nízkou lomovou houževnatost. Je sledováno šíření zárodečné povrchové trhliny ve směru k rozhraní, kde je trhlina odpuzována kovovým podkladem s vyšším Youngovým modulem, za použití metod lomové mechaniky. Je ukázáno, že vysoká tahová napětí indukovaná trhlinou v rozhraní, mohou vést k lokální dekohezi podél rozhraní, takže trhlina se může odklonit do rozhraní. (cs)
  • Plasma-sprayed ceramic coatings contain a high density of intrasplat microcracks, which are responsible for small Young’s 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’s 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.
