Production of Al2O3‐Stabilized Tetragonal ZrO2 Nanoparticles for Thermal Barrier Coating

“…To prevent the oxidation, delamination, cracking, spallation, and surface deterioration in high‐temperature atmosphere, the multilayer nanostructured coating is applied to various alloy substrates using Al 2 O 3 and ZrO 2 . However, this structural modification is difficult to achieve through the mono‐phase ceramic materials as well as by using a single‐ or double‐layer coatings . Generally, in multilayer coating, each layer functions as heat dissipater across the coating.…”

“…However, this structural modification is difficult to achieve through the mono-phase ceramic materials 18 as well as by using a single-or double-layer coatings. 19 Generally, in multilayer coating, each layer functions as heat dissipater across the coating. During this process, thermal conductivity tends to decrease linearly with increase in the number of structural layers.…”

“…Highly toughened ZrO 2 ‐based ceramics (Al 2 O 3 ‐ZrO 2 nanocomposite) are required for industrial coating applications. Techniques such as suspension plasma spray, atmospheric plasma spray (60:40 wt%), electron beam physical vapor deposition (85:15 mol%), gas tunnel plasma spray (80:20, 50:50, 20:80 wt%), and sol–gel deposition with atomic ratios of 7:93, 10:90, 30:70, and 38:62 are used for the preparation of Al 2 O 3 ‐ZrO 2 composite coating on the metallic substrate . Among different compositions, an improved microstructure performance of the composite is achieved when Al 2 O 3 and ZrO 2 contents are in the range of 40–90% and 10–60%, respectively.…”

Tetragonal and cubic zirconia multilayered ceramics: investigation of electrical parameters during automated EPD processing

“…1,2 Owing to its wide range of applications, zirconia coatings have attracted increased attention in the last years. 3,4 Several coating techniques as vapour deposition, 5 plasma spraying, 6 sol-gel 7 and casting techniques 8 have been proposed and studied to obtain optimal zirconia coatings. Another promising method to produce ceramic coatings and, more generally, hierarchically structured ceramic composites is electrophoretic deposition (EPD).…”
