Effects of air plasma spraying parameters on microstructure and bonding strength of GdPO4 thermal barrier coatings

Journal of Aeronautical Materials, 2022
With the increase of the turbine inlet temperature of gas engines, the widely used Y2O3 partially stabilized ZrO2（YSZ）thermal barrier coatings (TBCs) have been unable to meet the requirements, and new generation TBCs that can survive ultra high ...
