Some of the advanced techniques such as tomography are not commonly available and their resolution may be insufficient,as small microcracks have a crucial role in the coating properties and failure mechanisms.In this study, advantages of relatively simple direct in-situ microstructural observation of polished crosssections of thermal spray coatings during mechanical loading by means of scanning electron microscopy and subsequent strain-mapping analysis are Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2016
