“…However most of the initial titania reacted with alumina during the deposition process, leading to the formation of aluminium titanate (Al 2 TiO 5 ). This phenomenon has been previously reported for APS alumina-titania coatings with different TiO 2 content [38,40].…”

“…It has been shown that the addition of TiO 2 improves the coating fracture toughness in conventional APS coatings [36], usually obtained from fusing and crushing powders, as well as in coatings from nanostructured feedstocks which are commonly obtained by simple mixture of the oxides [37]. Indeed Al 2 O 3 -TiO 2 coatings obtained by APS from both conventional feedstocks and agglomerated powders has been extensively studied [38][39][40][41][42][43][44]. However, the research on SPS Al 2 O 3 -TiO 2 is still incipient and very few authors have studied such layers [45].…”

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.

“…The plasma sprayed coatings exhibit separate phases of Al 2 O 3 and understoichiometric TiO 2 as can be seen in micrographs. No forming of tialite (Al 2 TiO 5 ) has been observed, as could be expected from some studies presented in the literature [33].…”

Oxidative degradation of hazardous materials by ozone treatment like in sterilization of water, dump waste, pulp bleach and chemical processing, is superior to the traditional chlorine chemistry with respect to by-products and environmental protection. For an efficient and cost effective production of ozone for applications in drinking water and wastewater purification, a new concept of tubular composite material components has been developed. A borosilicate glass tube was coated with a layer system consisting of an intermetallic electrode and a dielectric oxide ceramic surface layer. Thermo-mechanical and dielectric properties are investigated with respect to the use of different thermal spray powders as well as the use of a high and a low energetic atmospheric spray gun. The materials and ozone production system of thermal sprayed ozonizer tubes are described and analyzed.

“…The test was conducted under following conditions: applied constant load of 10 N, radius from the center of the sample to pin of 6 mm, rotational speed of 60 rpm, duration of 1000s. AT-P0 and AT-P5 were composed of γ-Al 2 O 3 and Al 2 TiO 5 phases, along with compounds of AlPO 4 and Al(PO 3 ) 3 . However, the characteristic peaks of α-Al 2 O 3 phase do not appear in XRD spectrum of AT-P5.…”

Abstract. In the present study, Al 2 O 3 -40 wt.% TiO 2 composite coatings were fabricated on medium carbon steel substrate by plasma spraying technique. The coatings were sealed with aluminum phosphate solution containing 5 wt.% Al 2 O 3 nanoparticles and then heat treated at 400 o C. The phase composition, structure morphology, microhardness and wear resistance of the coating were studied. The study results phase composition of the coatings showed that the coatings were composed γ-Al 2 O 3 and Al 2 TiO 5 phase. The compounds AlPO 4 and Al(PO 3 ) 3 were found in the coating sealed with aluminum phosphate. The coatings sealed with aluminum phosphate containing Al 2 O 3 nanoparticles have lower porosity density, higher hardness and higher wear resistance than the coating sealed with aluminum phosphate uncontain Al 2 O 3 nanoparticles and the unsealed coating.
