Abstract

The paper presents an analysis algorithm for SEM images of HVOF-sprayed MCrAlY coatings as used in high-temperature environments. The grain size, orientation and deformation obtained for different oxygen fluence and different MCrAlY powders of spherical morphology are determined, in order to evaluate the coating process..

Keywords

Image processing, SEM, Grain size, Grain orientation, Grain form factor.
