High temperature Fatigue and Surface Engineering of IN718 Superalloy for Gas Turbines

A gas turbine is a type of internal combustion engine that converts the energy from burning fuel into mechanical energy. Gas turbines are known for their high power to weight ratio, making them suitable for aviation and power generation applications. In the aviation industry, gas turbines are commonly used in jet engines to provide the thrust necessary for flight. They are preferred due to their ability to operate at high altitudes and speeds efficiently. Generally, the gas turbines experience failure in their service on account of high thermal fatigue. Thermal fatigue occurs when materials are subjected to cyclic temperature changes, leading to mechanical stress and potential failure. Turbine blades and rotor discs are especially susceptible to thermal fatigue failure due to the combination of high temperatures and cyclic stresses they experience during operation. To mitigate gas turbine failure due to high thermal fatigue the use of high temperature resistant materials can improve the thermal fatigue resistance of turbine components.
