Abstract
The method according to the invention comprises a macrographic etching step followed by a “bleaching” step by electrolytic etching by means of a bath containing at least phosphoric acid and a weak acid. This method allows components made of superalloys to be easily and effectively inspected, including when they contain elements such as rhenium or ruthenium.
