The quality of plasma sprayed silicon coating determined by density and spreading condition lamella greatly influences its performance. oxidation deteriorates However, the investigators mostly focus on mechanism amorphous silicon, porous specific crystal planes single crystal. factors which influence has never be studied. helium secondary gas flow more than other spraying parameters. So, we pre...

Environmental barrier coatings are necessary to protect fibre reinforced ceramics from high recession rates in fast and hot water vapor-containing gases as they typically found the gas sections of turbines. A standard material SiC/SiC composites is atmospherically plasma sprayed (APS) Yb2Si2O7. For this material, it difficult obtain at reasonable substrate temperatures both low porosity crystal...

Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...

An AlCoCrFeNiY high-entropy alloy coating was prepared using air plasma spray. The cyclic oxidation behavior of the investigated and compared with that a conventional NiCoCrAlY coating. It is demonstrated exhibits much stronger resistance to spallation than when they are thermally cycled between room temperature 1050-1150 °C. difference attributed lower growth rate oxide scale on as result its ...
