Abstract

Abstract

The changes of surface coating, basic structures and mechanical proper-tie? in first stage turbine blade of GH220 alloy tested by engine rig for 236 hour? has been investigated. The results show that the structures of alloy are stable and properties of alloy still good. The isothermal treatment process at 1070℃ is suitable. It is shown that this alloy （blades） has greater potentiality.
