Another type of wear-like erosion is also prominent in turbine blades and vanes.

Major degradation such as abrasive wear and fretting fatigue wear are predominant mechanisms in combustion liners and transition pieces during start-stop or peaking operation, resulting in high cost if inadequately protected. C) in hot-gas-path systems and are generally subjected to heavy repair processes for maintenance works.These critical components are exposed to very high temperatures (ranging from 570 to 1300 Vital components such as combustion liners, transition pieces, blades, and vanes, which are often severely affected by wear, have been identified. In the gas-turbine research field, superalloys are some of the most widely used materials as they offer excellent strength, particularly at extreme temperatures.
