“…19,20 In contrast to the above powerful photocatalysts, a-Fe 2 O 3 /Bi 2 O 3 nanocomposites are grown on an iron substrate, which enables convenient recycling and produces no secondary pollution for no filtration procedure. 10 Considering the particular merits of the p-n heterojunction, various techniques have been employed to construct a-Fe 2 O 3based heterojunctions involving a chemical deposition method, 21 a sol-gel method, 22 and hydrothermal synthesis. 23,24 Among them, the hydrothermal method can be easily controlled by varying the reaction temperature and time.…”

“…In the literature, many reports concerning various ceramic materials produced via SG can be found, e.g., ZrO 2 -MgO nanocomposites [244], ultrafine alumina powders (<10 nm) [245], AlON powders by the nitritation of SG-derived alumina nanoparticles [246], nanoscale ZnTiO 3 powders [247]. In some papers, SG is paired with thermal spraying methods, of which plasma spraying is most recently applied.…”

Based on the recent analysis of various databases, cold spray (CS), the newest method among thermal spraying technologies, has received the unabated attention of hundreds of researchers continuously since its invention in the 1980s. The significance of CS lies in the low process temperature, which usually ensures compressive residual stresses and allows for the formation of coatings on a thermally sensitive substrate. This paper concerns the low-pressure cold spray (LPCS) variant employed for forming metal matrix composites (MMCs) with high ceramic contents and all-ceramic coatings. At the very beginning, the influence of LPCS process parameters on deposition efficiency (DE) is analysed. In the next part, the most useful feedstock powder preparation techniques for LCPS are presented. Due to the combination of bottom-up powder production methods (e.g., sol-gel (SG)) with LCPS, the metal matrix that works as a binder for ceramic particles in MMC coatings can be removed, resulting in all-ceramic coatings. Furthermore, with optimization of spraying parameters, it is possible to predict and control phase transformation in the feedstock material. Further in the paper, differences in the bonding mechanism of metal–ceramic mixtures and ceramic particles are presented. The properties and applications of various MMC and ceramic coatings are also discussed. Finally, the exemplary direction of CS development is suggested.

“…Organic phosphorus compounds are dissolved in ethanol whereas in most of the cases, water is employed during sol synthesis [101,102]. The phosphorus solutions are mixed slowly with the calcium salt solutions drop wise [103,104]. Calcium nitrate salt is mostly utilized as a calcium source in HAp.…”

Biomaterials are in use for the replacement and reconstruction of several tissues and organs as treatment and enhancement. Metallic, organic, and composites are some of the common materials currently in practice. Metallic materials contribute a big share of their mechanical strength and resistance to corrosion properties, while organic polymeric materials stand high due to their biocompatibility, biodegradability, and natural availability. To enhance the biocompatibility of these metals and alloys, coatings are frequently applied. Organic polymeric materials and ceramics are extensively utilized for this purpose due to their outstanding characteristics of biocompatibility and biodegradability. Hydroxyapatite (HAp) is the material from the ceramic class which is an ultimate candidate for coating on these metals for biomedical applications. HAp possesses similar chemical and structural characteristics to normal human bone. Due to the bioactivity and biocompatibility of HAp, it is used for bone implants for regenerating bone tissues. This review covers an extensive study of the development of HAp coatings specifically for the orthopaedic applications that include different coating techniques and the process parameters of these coating techniques. Additionally, the future direction and challenges have been also discussed briefly in this review, including the coating of HAp in combination with other calcium magnesium phosphates that occur naturally in human bone.
