Influence of alumina addition on steam corrosion behaviour of ytterbium disilicates for environmental barrier coating applications

چکیده
The sintering and steam corrosion behaviour of Yb2Si2O7 with without the addition Al2O3 has been studied on compacted specimens. While, to enhanced significantly, it also promoted formation a thin (80–100 nm), dense protective Yb3Al5O12 layer at surface when exposed steam. TEM analysis confirmed that is formed in environment via diffusion aluminium from residual present Al2O3/Yb2Si2O7 composite. These findings demonstrate benefit protect environmental barrier coatings corrosion.

Alumina nanostructured coating for corrosion protection of 316L stainless steel
Nanostructured alumina thin films were coated on stainless steel by Sol-Gel dip coating method. In order to prevent crack formation, Al2O3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. Effects of calcination temperature and withdrawal speed on structural properties were analyzed using XRD and SEM. Topography and thickness of coat...

متن کاملInfluence on Thermal Barrier Coating Delamination Behaviour of Edge Geometry
Ceramic thermal barrier coatings are commonly used in gas turbine hot components (e.g., combustor liners/buckets and guide vane platforms). In components that are only partially coated or have cooling-air outlets, coating-end stress singularities may lead to the spallation of the coating. Depending on the geometry of the transition from coated to uncoated material, the severity of the stress si...
