| Abstract: | A thermal barrier coating (TBC) consisting of CoNiCrAlY bonding layer and ZrO_2+Y_2O_3 surface layer was formed on the TiAl alloy surface by plasma spraying.The high temperature oxidation on the coating was tested and microstructure and micrograph of samples were investigated by SEM.The result showed that oxidation resistance of TiAl alloy after plasma sprayed is enhanced markedly. |
