You're an engineer working for a land-based gas turbine manufacturer. These turbines are similar to jet engines, but they are used onshore to provide power for power generation and gas compression pipeline applications. Operation of motor a ceramic-based thermal barrier to turbine blades in the first stage turbine to increase its temperature and efficiency suppose you want to apply a coating. By making the necessary associations between process-structure-property-performance describe in detail the following options. a) What do engineers like when trying to design a ceramic coating to be applied to a super alloy metal blade can you face difficulties? b) what properties should be considered when choosing a suitable ceramic material for a coating?
