热障涂层脱落对于叶片辐射温度场的影响

Gas turbine is an important symbol of national defense and economic strength.It plays an important role in the country's economic construction.As the gas turbine internal ambient temperature elevated,simply increase the manufacturing of high-temperature alloy turbine blade performance is not enough.Currently,beside the flow cooling,thermal barrier coating technology is used to improve the ability of resistance to high temperature turbine blades.But,the harsh working environments prone to thermal barrier coating damage.Now the main way to monitor the state of turbine blade is to take the radiation thermometry.In this paper,we verified the effects of the radiation temperature of the turbine blade thermal barrier coatings off in a lab environment and provides a reference.
