Ceramic thermal barrier coatings research for Progress

Recently, the Chinese Academy of Sciences , Changchun Institute of Applied Chemistry has made new progress in the design ideas of thermal barrier coatings , failure mechanisms and new thermal barrier coating materials research and development and other aspects of design and successfully prepared using a temperature ≥ 1250 ℃ double layer ceramic thermal barrier coating layer material .Washi tape


Changchun Institute of Technology researchers based at the international forefront of rare earth , carried out the design and failure mechanism of thermal barrier coatings , made a series of innovative research . Proposed rare earth materials and thermal barrier coatings applied by ion substitution ideas to improve the material properties ; -depth study of the thermal barrier coating of new materials and structures ,Sellotape

 invented a series of new rare earth -based high-temperature thermal barrier coating material that rare earth zirconate . On this basis , the researchers designed a temperature ≥ 1250 ℃ double ceramic layer , multi- layer and interface gradient ceramic thermal barrier coating material , which greatly improves the coating temperature and lifetime , breaking the 8YSZ (8wt% Y2O3 the temperature limit for the development of coatings for use at higher temperatures has opened up a new way.Wholesale masking tape


Ceramic thermal barrier coating technology utilizes high insulation material and corrosion resistance to protect the metal substrate in the energy , aviation, aerospace and other aspects have a significant value. Conventional thermal barrier coating material 8YSZ stabilized ZrO2) upon the occurrence of phase transitions at high temperatures , sintering, and oxygen , can not withstand the high temperature 1200 ℃ above . Currently, research efforts around the world are able to replace 8YSZ, thermal barrier coating material can be used at higher temperatures .

The outcome has been four patents at home and abroad , published a monograph on the professional core journals Adv Mater and J Eur Ceram Soc magazine published a series of high impact papers.Masking tape
