Turbines with good oxidation and corrosion resistance are of great significance in many fields. For example, in the aerospace field, aircraft engine turbines need to work in high temperature, high pressure and complex chemical environments, and strong oxidation and corrosion resistance can ensure long-term stable operation of turbines, reducing failure and maintenance costs.

In industrial power generation, for example, turbines in gas turbines face similar challenges. If the anti-oxidation and anti-corrosion performance of the turbine is insufficient, it may lead to reduced efficiency, component damage, and even shutdown for maintenance, which will bring huge losses to production.
In order to achieve good oxidation and corrosion resistance of turbines, the following aspects are usually started:
Material innovation: The development and use of new superalloy materials, which have been specially formulated and treated to provide excellent oxidation and corrosion resistance.
Surface treatment technology: Various advanced surface coatings, such as thermal barrier coating and cermet coating, are used to enhance the protective ability of turbine surface.
Optimization design: Through reasonable structural design, improve the airflow inside the turbine, reduce local high temperature and corrosion concentration area.
