The study on porosity and thermophysical properties of nanostructured La2Zr2O7 coatings

► Nanostructured lanthanum-zirconium coatings were deposited by air plasma spraying. ► The pore size distribution and buck density of coatings were identified by mercury intrusion porosimetry. ► The thermophysical properties of the nanostructured coatings were also examined through laser flash technique and differential scanning calorimetry.
