“…The preferable particle size of the feedstock used in APS ranges from 10-140 µm. It was found that with the use of nano sized powders, improvement in thermal shock resistance can be obtained due to the lower tensile stress in plane and higher fracture toughness of nanostructured layers [30][31][32]. However, feeding of powders below 10µm into a plasma jet is considered near impossible and agglomerated nano powders retain only a little of their original structure in the final coating [33][34].…”

“…The double-layer system showed a similar to or slightly better performance than that of YSZ coatings at temperatures below 1300°C, suggesting the double-layer coating with YSZ is an effective way to improve the lifetime of TBC in thermal cycling tests [62]. Meanwhile, Cao et al also showed that the single-layer LZ coating had a short thermal cycling lifetime, but the double-layer LZ coating with La2O3-ZrO2-CeO2 composite sublayer can greatly improve the lifetime [63]. However, the more layers that the TBC coating has, the more artificial defects might be generated during the deposition process.…”

This review article summarizes the latest information about the manufacturing techniques of lanthanum zirconate (La2Zr2O7, LZ) 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. In this work, the physical, thermal, and mechanical properties of the powder and coatings are evaluated. The durability experiments of the TBCs in various thermal, mechanical, and corrosive conditions is also reviewed. In addition, theoretical studies on the powder and coatings properties are presented. Finally, future research directions of lanthanum zirconate as TBC applications are proposed.

“…By using DSC and DMTA, Zabihi et al [182] also found that Fe 2 O 3 nanoparticles improved the crosslink density of epoxy, as evidenced by the increase in the glass transition temperature. In case of inorganic matrices, for thermal sprayed coatings, the nanocomposite structure had higher thermal shock resistance than the conventional structure [183,184].…”

Incorporation of nanofillers into the organic coatings might enhance their barrier performance, by decreasing the porosity and zigzagging the diffusion path for deleterious species. Thus, the coatings containing nanofillers are expected to have significant barrier properties for corrosion protection and reduce the trend for the coating to blister or delaminate. On the other hand, high hardness could be obtained for metallic coatings by producing the hard nanocrystalline phases within a metallic matrix. This article presents a review on recent development of nanocomposite coatings, providing an overview of nanocomposite coatings in various aspects dealing with the classification, preparative method, the nanocomposite coating properties, and characterization methods. It covers potential applications in areas such as the anticorrosion, antiwear, superhydrophobic area, self-cleaning, antifouling/antibacterial area, and electronics. Finally, conclusion and future trends will be also reported.
