“…Nanostructured materials have been extensively studied in the past decades [1][2][3] showing that nanostructure significantly increases material performances [4][5][6]. In particular, nanostuctured coatings are expected to provide several industries with enhanced components leading to better properties and longer lifetime [7][8][9].…”

Versión / Versió:Preprint were used as starting materials. The coatings microstructure and phase composition were fully characterised using FEG-SEM and XRD techniques. Nanoindentation technique was used to determine the coatings hardness and elastic modulus properties.Results have shown that the addition of titania to alumina SPS coatings causes different crystalline phases and a higher powder melting rate is reached. The higher melted material achieved, when titania is added leads to higher hardness and elastic modulus when the same spraying parameters are used.

“…Nanostructured materials represent an enhanced version of their conventional counterparts (Ref 1, 2) and usually exhibiting better performances (Ref [3][4][5]. Bulk nanomaterials are being extensively studied but also nanostructured coatings on conventional materials are investigated as they have the potential of providing several industries with novel materials with improved properties and prolonged lifetime .…”

Al 2 O 3 -13%TiO 2 coatings were deposited on stainless steel substrates from conventional and nanostructured powders using atmospheric plasma spraying (APS). A complete characterization of the feedstock confirmed its nanostructured nature. Coating microstructures and phase compositions were characterized using SEM, TEM, and XRD techniques. The microstructure comprised two clearly differentiated regions. One region, completely fused, consisted mainly of nanometer-sized grains of c-Al 2 O 3 with dissolved Ti +4 . The other region, partly fused, retained the microstructure of the starting powder and was principally made up of submicrometer-sized grains of a-Al 2 O 3 , as confirmed by TEM. Coating microhardness as well as tribological behavior were determined. Vickers microhardness values of conventional coatings were in average slightly lower than the values for nanostructured coating. The wear resistance of conventional coatings was shown to be lower than that of nanostructured coatings as a consequence of Ti segregation. A correlation between the final properties, the coating microstructure, and the feedstock characteristics is given.

“…Also the wear of the hardmetals was studied using carbides with various cobalt contents and hence various microstructures were found [3,4]. In some studies wear was simulated by scratching the surface in a controlled way [5,6].…”
