ABSTRAKT

A combination of two techniques was implemented to quantify the morphology and the connectivity of the complex pore-crack network architecture of thermal sprayed coatings:

  • image analysis coupled to stereological protocols permits to quantify the coating porous morphology, that is to say the porosity level (with a discrimination between globular pores and cracks), the orientation and the linear density of cracks;
  • electrochemical impedance spectroscopy permits to quantify the pore connectivity (the open porosity level).
These techniques were applied to characterize the pore structure of grey alumina (Al2O3-13TiO2) coatings and Yttria-Partially Stabilized Zirconia (Y-PSZ) Thermal Barrier Coatings (TBCs), respectively manufactured implementing air plasma spraying and hybrid plasma spraying (which combines plasma spraying and in situ laser remelting).
