Abstrakt: This study concerns the mechanical properties of CoNiCrAlY-BN-Polyester composite coatings elaborated by Atmospheric Plasma Spray (APS) and used as abradable seals in the aeronautic industry. The objective is to determine the influence of the diameter of the plasma torch on the coating micrograph morphologies and on the resulting coating thermal and mechanical effective properties. The thermo-mechanical effective properties were then estimated by Finite Element modelling (thanks to the multipurpose finite element software ANSYS) based on coating microstructures captured by Scanning Electron Microscopy (SEM) and Optical Microscopy (OM)
