Abstract Refurbishment of thermal barrier coating (TBC) has become a valuable technique to prolong the service life
of high-temperature components. In this work, the effect of refurbishment process on the oxidation
behaviors of TBC was investigated. Before recoating, the soft chemical stripping method was used to remove
TBC from DD6 single-crystal superalloy. The results showed that a certain amount of IDZ layer with Cr-rich
would be retained in the DD6 superalloy substrate after coating removal. The characteristics of the β phases
change from the elongated grain shapes and a high aspect ratio in the ordinary specimens… More >
