Abstract Suspension plasma spraying (SPS) and spray-physical vapor deposition (PS-PVD) are the only thermal spray technologies shown to be capable of producing TBCs with columnar microstructures similar electron beam-physical (EB-PVD) process but at higher rates relatively lower costs. The objective this study was achieve fundamental understanding effect different produced by these two processe...

Solution precursor plasma spray (SPPS) can prepare thermal barrier coatings (TBCs) with nanostructures, which modify the adhesion and wettability of molten silicate environmental deposits (CMAS) on surface TBCs, thereby improving resistance TBCs to CMAS corrosion. In this study, SPPS layers micro-nano double scale structures were prepared conventional atmospheric spraying (APS) coatings. The ef...

Abstract A solid oxide fuel cell (SOFC) with a liquid antimony anode (LAA) is potential energy conversion technology for the use of impurity-containing fuels. Atmospheric plasma spraying (APS) has become promising LAA-SOFC preparation method because its economy and convenience. In this paper, button SOFCs different cathode materials ratios pore former were prepared by APS operated at 750 °C. Th...

A process implying the pre-oxidation of nickel substrates was proposed alternatively to usual Atmospheric Plasma Spraying (APS) alumina on sandblasted substrates. This comprised two steps, substrate (instead sandblasting substrate) followed by APS. The formed a thin layer NiO oxide, 0.7–3.5 ?m thick, which entirely covered substrate. During APS, deposit did not react with due very high cooling ...

From the literature, it is known that due to their glass formation tendency, it is not possible to deposit fully-crystalline silicate coatings when the conventional atmospheric plasma spraying (APS) process is employed. In APS, rapid quenching of the sprayed material on the substrate facilitates the amorphous deposit formation, which shrinks when exposed to heat and forms pores and/or cracks. T...

Coatings prepared from nanosized powders were obtained by spraying ethanol-based colloidal solutions into a plasma plume. The powders investigated included 40 nm γ -Al2O3, 75 nm 8 wt% Y2O3-ZrO2, and 750 nm 25 wt% CeO2-ZrO2. Spray distances from approximately 50 to 63 mm were required to achieve significant coating deposition. As observed in the TEM, the typical lamella morphology of air plasma ...

in this study, hydroxyapatite was coated on titanium substrates by plasma spraying process. a well-known porous and lamellar microstructure was found in the lateral and outer surface of coating. the phase composition was studied by xrd and the morphological and the microstructural aspects were investigated by scanning electron and optical microscopy. the hardness of coatings and substrates was ...

Plasma-sprayed Yttria-stabilized zirconia (YSZ) coatings have been used in gas turbines for decades. They are applied thermal insulation to increase operating temperature and hence efficiency component’s lifetime. To keep manufacturing costs low, especially deposition is important. However, increasing it also related a reduction porosity, affecting the insulating properties of layer. find an op...
