Thermal barrier coating

Thermal barrier coating is an advanced material and generally used in metal surface, such as gas turbines and engine parts, often in the ultra-high temperature environment, whcih can be seen as a waste heat management. Thermal barrier coatings through its work isolate the alloy ultra-high temperature heat source nearby, making the overall system performance is improved, so that makes structural components thermal fatigue and oxidation resistance are improved. Thermal barrier coatings (Thermal Barrier Coating) is a layer of ceramic coating, it is deposited in the high-temperature super- alloy metal or surfaces, thermal barrier coatings to the substrate material for heat insulation effect, reducing the substrate temperature, making its use made the device ( eg engine turbine blades ) can be run at high temperatures, and can improve the device ( engine, etc. ) more than 60% thermal efficiency.

Currently more use in the aerospace, aviation, power generation, automotive and other industries. With the aviation, aerospace and civilian technology development, the use of temperature hot end parts have become increasingly demanding, in order to achieve high-temperature alloys and single crystal materials under extreme conditions. Heating of the fuel turbine components such as nozzles, blades, combustion chamber, for example, they are in a high-temperature oxidation and high temperature gas stream erosion and other harsh environment, withstand temperatures up to 1100℃, high temperature nickel alloys have been used over the limit temperature (1075℃). The metal of high strength, high toughness and high-temperature ceramics prepared by combining a bit out of the thermal barrier coating to solve the above problems, it can heat insulation, anti-oxidation, anti-corrosion effect, has been in the turbine, diesel generator, jet engines and other materials to obtain a hot end of the application, and improves the life of the hot end parts.
