TL;DR: In this paper, the influence of nanostructured materials on important areas, such as, thermal barrier coatings (TBCs) and biomedical coatings was investigated, and it was determined that by controlling the distribution and character of the semi-molten nanozones embedded in the coating microstructure, it was possible to engineer coatings that exhibited high toughness for anti-wear applications or highly friable for use as abradable, exhibiting abradability levels equivalent to those of metallic-based abradables.

TL;DR: In this paper, the cold-spray process was used to prepare nanostructured WC-Co coatings and the coating microstructural characteristics and phase composition were analyzed via optical microscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD).

TL;DR: In this article, nanostructured and conventional YSZ coatings were heat-treated at 1400°C for 1, 5 and 20h, respectively, and the thermal diffusivity and elastic modulus values were significantly lower than those of conventional yttria coatings, even after an exposure to a temperature of 1400 ˚ c for 20h.

TL;DR: In this article, the authors presented two spray techniques used for manufacturing nanostructured coatings: thermal plasma and HVOF sensors developed for in-flight diagnostics of micrometre-sized particles and the interaction of a liquid and hot gas flow.

TL;DR: In this paper, the microhardness and roughness of the nanostructured zirconia (PSZ) feedstock was investigated and it was found that roughness is an indicator of the coating state that reflects the intrinsic microstructure of the coatings.
