Today's state-of-the-art aero engines operate at temperatures above 1,700 degrees Celsius, and this extraordinary high temperature is supported by the three major thermal insulation technologies of aero engines: single crystal alloy, air film cooling and thermal barrier coating technology. When the cooling effect of the air film reaches its limit, the thermal barrier coating takes all the responsibility, so the thermal barrier coating is called the most important "protective clothing" of aero engines.

Thermal barrier coatings are often used for high temperature protection and are one of the hot spots in the field of coating research in recent years. Thermal barrier coatings have many advantages, such as reducing the operating temperature of components and thus reducing damage caused by fatigue, and reducing the cooling gas requirements of turbine blades, helping to improve engine efficiency and extend operating life.

Thermal barrier coatings have a sandwich-like multi-layer structure consisting of a ceramic insulation, a metal bond, and a superalloy base layer. Despite their "sandwich" shape, thermal barrier coatings are not simply layered, but by evaporating the material to be coated into steam or fine into particles with a diameter of microns, which are then firmly coated on the surface of the material through crystallization growth or with the help of extremely high energy.

The thermal barrier coating is usually composed of a metal bonding bottom layer and a ceramic surface layer, the bonded bottom layer is usually made of MCRARY (M is Ni, CO or Ni+CO) alloy, which is mainly responsible for the multiple functions of transition heat mismatch, oxidation resistance and corrosion resistance, while the ceramic surface layer usually uses Y2O3 stable ZRO2, which mainly plays the role of heat insulation, because of its good high temperature oxidation resistance, erosion resistance and heat insulation, it has become one of the most advanced high temperature protective coatings for ground heavy-duty gas turbines at home and abroad.

With the development of the aviation industry, the thrust-to-weight ratio of turbine engines is getting higher and higher, and the temperature of the pre-turbine inlet is also getting higher and higher. According to the research process of materials at home and abroad, it is quite difficult to improve the high temperature resistance of turbine blades by increasing the use temperature of materials in a short period of time, and the feasible method is to deposit thermal barrier coating on the turbine blade matrix to increase its service temperature.

Why does the thermal barrier coating withstand such high temperatures and become a "protective suit" for aero engines and heavy-duty gas turbines? What are the most widely used types of thermal barrier coatings today? What is the extent of the relevant fields at home and abroad? Should we break through from ** in the future?

In order to accelerate the exchange and cooperation in the direction of high temperature resistance of aero engines and heavy-duty gas turbines, the 2024 Turbo Technology Expo, the largest exhibition in the field of aero engines and gas turbines in Asia, will have a special CMC sub-forum on ceramic matrix composites.
