“…The solution precursor spraying is intensively developed and the recent study shows e.g., the compositionally graded and porosity graded coatings [181], doping of solution precursors by rare-earth elements [182] and by metal ions [183,184].…”

The paper briefly describes major thermal spray techniques used to spray functionally graded coatings such as atmospheric plasma spraying, high velocity oxy-fuel spraying, suspension and solution precursor plasma spraying, and finally low and high pressure cold gas spray method. The examples of combined spray processes as well as some examples of post spray treatment including laser and high temperature treatments or mechanical one, are described. Then, the solid and liquid feedstocks used to spray and their properties are shortly discussed. The reviewed properties of functional coatings include: (i) mechanical (adhesion, toughness, hardness); (ii) physical (porosity, thermal conductivity and diffusivity, thermal expansion, photo-catalytic activity), and; (iii) bioactivity and simulated body fluid (SBF) corrosion. These properties are useful in present applications of functionally graded coatings as thermal barriers, the bioactive coatings in prostheses, photo-catalytic coatings in water treatment, coatings used in printing industry (anilox and corona rolls). Finally, some of the future possible fields of functional thermal sprayed coatings applications are discussed, e.g., to coat polymer substrates or to use the cheap technology of low pressure cold gas spray method instead of expensive technology of vacuum plasma spraying to obtain bond coatings.

“…[36,37] In the zirconate synthesis, alkaline-earth oxide (AO) and ZrO 2 are first formed, desirably reacting to give the perovskite. [38] However, the AO may react with the CO 2 from the combusted organic components to give the carbonate. [38] Carbonate can endothermically decompose to CO 2 and AO, [39,40] and the latter can react with ZrO 2 to give the AZrO 3 perovskite (e.g., A = Ba, Ca, or Sr).…”

[ 38 ] The decomposition activation energies, and in practice, decomposition temperatures, increase with the atomic number (CaCO 3 < SrCO 3 < BaCO 3 ) and depend on the crystalline carbonate form, which can end up varying the physical–chemical characteristics and structural architecture of the aimed 3D perovskite.…”

“…[42] A way forward is to compensate for composition inhomogeneities; an excess amount of A-rich components, such as an excess of Sr, Ba, or Ca, is sometimes used to compensate for carbonate formation. [38,43] To our knowledge, the AM of 3D perovskite architectures with sub-micrometer sizes has not yet been presented. Hence, this work introduces a library of 3D architected alkaline-earth zirconates of (sub-)micrometer sizes additively manufactured using tailor-made photoresists suitable with TPL.…”

Three‐dimensional (3D) ceramic architectures are captivating geometrical features with an immense demand in photonics. Here, we develop an additive manufacturing (AM) approach for printing alkaline‐earth perovskite 3D microarchitectures. The newly developed approach enables custom‐made photoresists suited for two‐photon lithography, permitting the production of alkaline‐earth perovskite (BaZrO3, CaZrO3, and SrZrO3) 3D structures shaped in the form of octet‐truss lattices, gyroids or inspired architectures like sodalite zeolite, and C60 buckyball with micrometric and nanometric feature sizes. Alkaline‐earth perovskite morphological, structural, and chemical characteristics are studied. The optical properties of such perovskite architectures are investigated using cathodoluminescence and wide‐field photoluminescence emission to estimate the lifetime rate and defects in BaZrO3, CaZrO3, and SrZrO3. From a broad perspective, our AM methodology facilitates the production of 3D‐structured mixed oxides. Our findings are the first steps toward dimensionally‐refined high refractive index ceramics for micro‐optics and other terrains like (photo)catalysis.This article is protected by copyright.
