Progress update on extending the durability of air plasma sprayed thermal barrier coatings
نویسندگان
چکیده
Air plasma sprayed thermal barrier coatings (TBCs) are widely used in gas turbines to provide insulation for the metallic engine components. During service, multi-layered and multi-material systems undergo mechanical degradation. The degradation mechanisms include sintering, phase transformation, residual stress, oxidation, erosion CMAS attack. leads initiation propagation of cracks at or near interface between topcoat bond coat, eventually merging into large-scale delamination resulting failure TBCs. Recent progress development methods mitigating detrimental impact these via composition processing modifications has been reviewed. Meanwhile, applications newly-emerging materials with superior properties have also discussed. review emphasises relationships composition, microstructure TBCs, which is beneficial exploration advanced TBCs higher durability.

Thermal Conductivity Analysis and Lifetime Testing of Suspension Plasma-Sprayed Thermal Barrier Coatings
Suspension plasma spraying (SPS) has become an interesting method for the production of thermal barrier coatings for gas turbine components. The development of the SPS process has led to structures with segmented vertical cracks or column-like structures that can imitate strain-tolerant air plasma spraying (APS) or electron beam physical vapor deposition (EB-PVD) coatings. Additionally, SPS coa...
متن کاملMonitoring Delamination of Plasma-Sprayed Thermal Barrier Coatings by Reflectance-Enhanced Luminescence
Highly scattering plasma-sprayed thermal barrier coatings (TBCs) present a challenge for optical diagnostic methods to monitor TBC delamination because scattering attenuates light transmitted through the TBC and usually degrades contrast between attached and delaminated regions of the TBC. This paper presents a new approach where reflectance-enhanced luminescence from a luminescent sublayer inc...

متن کاملFormation of vertical cracks in solution-precursor plasma-sprayed thermal barrier coatings
When tailored to make durable thermal barrier coatings (TBCs), the Solution Precursor Plasma Spray (SPPS) process produces a microstructure containing uniformly vertical cracks. These cracks provide a high degree of strain tolerance to the ceramic top coat. In order to understand the formation of vertical crack in SPPS process, coatings of various thicknesses were deposited on a variety of subs...
