Properties of Lanthanum Zirconate–Based Thermal Barrier Coatings

This chapter summarizes the latest information about the manufacturing techniques of lanthanum zirconate (La2Zr2O7) powder and La2Zr2O7-based thermal barrier coatings (TBCs). Lanthanum zirconate is a promising candidate material for TBC applications due to its lower thermal conductivity and higher thermal stability compared to other traditional TBC systems. The physical, thermal, and mechanical properties of the powder and coatings are presented. The durability assessment of the coatings in various thermal, mechanical, and corrosive conditions is also reviewed.
