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 ...

Atmospheric plasma sprayed (APS) coatings of Al2O3–TiO2 system for photocatalytic application
Photochemical & Photobiological Sciences, 2009The 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.

Tribological Behaviour of Abradable Coatings Obtained by Atmospheric Plasma Spraying (APS)
International Thermal Spray Conference, 2001Abstract Actually abradable coatings obtained by thermal spraying are currently used in aeronautical industry. They improve the turbines tightness increasing in that way, their yield. The most relevant property of this kind of coatings is its easy machinability.

Tribological Features of Self-Lubricated Coatings Obtained by Atmospheric Plasma Spraying (APS)
International Thermal Spray Conference, 2002Abstract This study analyzes the tribological behavior of nickel-graphite and aluminum-silicon-polyester thermal sprayed coatings and the effect of non-metallic compounds. Self-lubricating coating composites based on a metallic matrix with ceramic or polymeric filler phases show potential applications requiring high wear resistance and ...

The atmospheric plasma spraying (APS) process can be divided into sub-processes, which are simulated by different numerical methods. The balance equations of momentum, mass and energy of the plasma jet are solved numerically by applying the finite volume method (FVM) using a CFD (Computational Fluid Dynamics) software tool.
