High-entropy alloys (HEAs) have great potential to be used as high-temperature materials and in coating material applications due their combination of strength, ductility, thermal stability, wear, oxidation resistance. In this work, a new HEA alloy based on NiCoCrAlSi composition was designed deposited into metallic coatings by high-velocity oxy-fuel (HVOF) air plasma spray (APS) processes, wit...

A low-cost manufacturing procedure has been developed for the fabrication of planar anode-supported solid oxide fuel cell including only two thermal treatments. This method is also environmental-friendly since slurries are water based and use non-toxic additives. Slurries were formulated by optimizing powder quantity, minimizing organic compounds while controlling their stabilities rheological ...

SOFC solid electrolytes are known for their ionic conductivity characteristics, which increase with increasing operating temperature. Using COMSOL Multiphysics numerical simulation, analysis of power performance yttria-stabilized zirconia (YSZ) and lithium sodium carbonate – gadolinium-doped ceria ({LiNa}2CO3-GDC) was conducted to determine the potential these in application SOFC. The YSZ diffe...

The preparation of thermal barrier coatings (TBCs) is a complex process involving the integration physics and chemistry, mainly flight behavior deposition molten particles. service life performance TBCs were determined by various factors, especially parameters. In this work, to set up quantitative characterization model between parameters characteristic parameters, ceramic powder particle size,...

The present study focuses on an alternative structured oxygen electrode for solid oxide electrolysis cells (SOECs). La2NiO4+δ nickelate, LNO, was selected with respect to its mixed electronic and ionic conductivity good chemical stability. Complete single were built using screen printing of LNO LaNi0.6Fe0.4O3 (LNF) layers a standard hydrogen supported half cell consisting porous NiO-YSZ layer, ...

ZrO2-YO1.5-TaO2.5 (ZYTO) composite ceramics are considered to be a candidate for next-generation thermal barrier coatings (TBCs) due their excellent stability and low conductivity in high temperatures; however, the mechanical properties fracture toughness of ZYTO system may shortcomings compared with 7-8YSZ: traditional TBC. In this study, were successfully prepared by chemical coprecipitation ...
