prepared spray coating is still up for debate, as metallographic grinding and polishing, if not carried out correctly, can introduce artefacts which are not part of the coating structure. for example, in metal or metal/ceramic coatings, the softer metal is smeared into pores during grinding and, if not polished
properly, can cover up the true porosity. in comparison, ceramic coatings are brittle and particles break out of the surface during grinding. if not polished thoroughly, these particles leave an incorrect impression of high porosity. in general, common difficulties with preparing thermal spray coatings...
