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.
