Kvantifikace struktury žárovových nástřiků s pomocí objemové rekonstrukce
 Ctibor, Pavel ; Lechnerová, R. ; Hofmann, P.
The paper introduces a way to study structure of thermally sprayed coatings in detail. Two microstructures are compared, which originate from two different spraying techniques used for the same material. The material selected is stainless steel AISI 316L and the techniques are plasma spraying using water-stabilized plasma gun and wire arc spraying. A sophisticated analytical technique is applied which was developed for a 3D reconstruction of the architecture of thermally sprayed coatings, revealing their main characteristic structural features such as porosity and oxide phase. The technique is called 3D mapping and describes the shape of pores, their interactions, etc. It is based on optical microscopy and software treatment of microstructural images. Also it is possible to detect pores or the structural phases, provided that they can be separated by proper threshold. This method is here applied first time on wire arc sprayed coating and also on metallic coating containing oxides.
