“…Solution precursor plasma spraying (SPPS) allows for manufacturing coatings with submicrometer and nanometer structures. Examples of the coatings obtained with SPPS include thermal barrier coatings (Yang et al, 2020), nanostructural photocatalytic coatings (Dom et al, 2012), hydrophobous rare earth coatings (Xu et al, 2021), coatings for solid oxy-fuel cells (Shri Prakash et al, 2017), environmental barrier coatings (Darthout et al, 2016), bioactive glass coatings (Canas et al, 2019;Garrido et al, 2021), coatings for gas sensors (Yu et al, 2017), etc. The precursors applied to spraying are generally mixtures of compounds, such as salts, acetates, or nitrates, dissolved in a solvent (usually an organic liquid or water) to form a final solution (Łatka et al, 2020).…”

“…Subsequently, many coatings for different applications were sprayed by SPPS. The examples are: thermal barrier coatings (TBC) [54,55], coatings solid oxy-fuel cells [56,57], biomaterial coatings [58,59], photocatalytic coatings [60,61], coatings for gas sensors [62,63], environmental barrier coatings [64], and many others.…”

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.

“…For example, SPPS-sprayed Y2SiO7 environmental barrier coating (EBC) at a long distance of 140 mm showed a loose columnar structure on a relatively smooth substrate [24]. The state of feedstock (from gas to liquid to solid) and the incidence angle at the moment of impact on the substrate both play important roles, as columnar structures also form from the vapor phase in PS-PVD [10].…”

“…The intracolumnar porosity is formed by incomplete sintering of lamellae and coalescence of pores. Pores are caused by the random stacking of impinging particles [24]. When the impinging agglomerated particles possess various morphologies, the stacked coatings may show different intracolumnar porosities.…”
