K3Fe(CN)6 was added in as a water-soluble electroactive probe, and its electrochemical behavior......
compared with as-aluminized bond coats. However, the wavelength of TGO undulations shows a little increasing trend. From further study, the polishing treatment bond coats show better TGO adherence and lower alumina growth rate. Key words: platinum; aluminide bond coats; high temperature oxidation; polishing treatment  ......
