“…For example, TBCs represent one of the most important coating layers in engines and turbines for prevention of degradation of these components. Also, electrically insulating materials are required in metallurgical processes including electrically assisted forging (EAF) and electrically assisted manufacturing (EAM) . In these cases, various ceramic materials (e.g., aluminum oxide (Al 2 O 3 ), titanium dioxide (TiO 2 ), and zirconium dioxide (ZrO 2 )) have been used, as they meet the requirements for insulating materials, i.e., possess high melting temperatures, experience no phase changes under operating conditions, have low thermal conductivities and diffusivities, and similar thermal expansion coefficients to those of metals .…”

Supersonic cold spraying is an emerging technique for rapid deposition of films of materials including micron-size and submicron metal particles, nanoscale ceramic particles, clays, polymers, hybrid materials comprised of polymers and particulates, reduced graphene oxide (rGO), and metal-organic frameworks. In this method, particles are accelerated to a high velocity and then impact a substrate at near ambient temperature, where dissipation of their kinetic energy produces strong adhesion. This manuscript reviews the recent progress in fundamentals and applications of cold spraying. High velocity impact with the substrate results in significant deformation, which not only produces adhesion, but can change the particles' internal structure. Cold-sprayed coatings can also exhibit micro-and nanotextured morphologies not achievable by other means. Suspending micro-or nanoparticles in a liquid and cold-spraying the suspension produces fine atomization and even deposition of materials that could not otherwise be processed.

“…PAD can be used to deposit not only protective or insulating layers such as alumina [45] but also other functional materials such as ion conductors [46][47][48][49][50][51][52] or thermoelectric materials [53,54]. The suitability of such layers for sensor applications, also with YSZ as solid electrolyte, has already been demonstrated [55,56].…”

Powder aerosol deposition (often abbreviated as PAD, PADM, or ADM) is a coating method used to obtain dense ceramic films at room temperature. The suitability of this method to obtain ammonia mixed-potential sensors based on an yttria-stabilized zirconia (YSZ) electrolyte that is manufactured using PAD and a V2O5–WO3–TiO2 (VWT)-covered electrode is investigated in this study. The sensor characteristics are compared with data from sensors with screen-printed YSZ solid electrolytes. The PAD sensors outperform those in terms of sensitivity with 117 mV/decade NH3 compared to 88 mV/decade. A variation in the sensor temperature shows that the NH3 sensitivity strongly depends on the sensor temperature and decreases with higher sensor temperature. Above 560 °C, the characteristic curve shifts from exponential to linear dependency. Variations in the water and the oxygen content in the base gas (usually 10% oxygen, 2% water vapor in nitrogen) reveal a strong dependence of the characteristic curve on the oxygen content. Water vapor concentration variations barely affect the sensor signal.
