Atmospheric plasma sprayed (APS) coatings of Al2O3–TiO2 system for photocatalytic application
Photochemical & Photobiological Sciences, 2009 The goal of this study is to examine the photocatalytic ability of coatings produced by atmospheric plasma spraying (APS). The plasma gun used is a common gas-stabilized plasma gun (GSP) working with a d.c. current and a mixture of argon and hydrogen as plasma-forming gas.

In this work, silicon coatings were deposited using VPS and APS technologies. Their structure and composition were characterized using XPS, SEM, and XRD. The porosity and surface-roughness of coatings were evaluated. The results showed that the VPS silicon coating possessed lower porosity compared with the APS silicon coating.

Abstract High amorphous phase formation tendency, a desirable microstructure and phase composition and silicon evaporation are the challenges of spraying Yb2Si2O7 environmental barrier coatings (EBCs). This research addresses these issues by depositing as-sprayed high crystalline Yb2Si2O7 using atmospheric plasma spray (APS) without any ...

Abstract Normally the conventional thermal spray processes as the atmospheric plasma spraying (APS) have to use easily flowable powders in a size range between 10 and 100 µm. In contrast the suspension plasma spraying (SPS) makes it possible to process nano sized particles directly.
