Effect of ion implantation on growth of thermally grown oxide in MCrAlY coating for TBC
Thermal barrier coatings (TBCs) have been widely used in various gas turbines for aircraft propulsion and power generation. TBCs consist of a metal bond coat and a ceramic top coat of YSZ. It is generally known that the TBC′ life strongly depends on the thermally grown oxide (TGO) because failure of...

description | Thermal barrier coatings (TBCs) have been widely used in various gas turbines for aircraft propulsion and power generation. TBCs consist of a metal bond coat and a ceramic top coat of YSZ. It is generally known that the TBC′ life strongly depends on the thermally grown oxide (TGO) because failure of TBCs occurs when the TGO reached a critical thickness. In this study, ion implantation of novel elements has been made on the bond coat which acts as an oxidation barrier for suppressing the TGO growth. The effects of type of ion implanted elements on the TGO formation were investigated. The oxidized specimens at 1150
°C were characterized by SEM, XRD, RBS and AES. From the results, CoNiCrAlY bond coat with an oxidation barrier was found to be effective in suppressing growth of the TGO. |
