Originální abstrakt

Modern thermal barrier coating systems (TBCs), see Fig. 1, usually consist of nickel or cobalt based substrate alloy, adjacent (inter)metallic bond coat (Pt-Al or M-CrAlY, where M substitutes Ni, Co or their appropriate combination) and outer ceramic top coat (ZrO2+6-8%Y2O3) [1]. As the bond coats are primarily applied to protect the underlying metallic substrate against the oxidizing and hot-corrosive environment, the principal function of TBC, as its name suggests, is to reduce the metallic substrate temperature and thereby either increase the service life of the component or allow for higher combustion temperatures, which translates into increased aerospace engines efficiency. The aim of this work is to focus on differences in formation and growth of TGO at two types of TBCs (ceramic top coats) produced by means of atmospheric and/or water stabilized plasma spraying after the isothermal exposure at the temperature of 900 and 1050°C.
