متن کاملPlasma spraying of micro-composite thermal barrier coatings
The thermal barrier coatings (TBCs) by gas tunnel-type plasma spraying exhibited ceramic-composite features consisting of a host oxide matrix ceramic with an embedded second phase material. The densities of the composite TBC were found to be higher than those sprayed with 100wt% ZrO2 or Al2O3. In the coatings produced with powder mixtures of 50wt%, the embedded splats are found to have a relati...
متن کاملManufacturing nanostructured YSZ coatings by suspension plasma spraying (SPS): effect of injection parameters
The suspension plasma spraying process is investigated by using shadow imaging techniques to appreciate the different trajectories of the liquid jet interacting with a DC highenergy plasma flow. Then, the modelling of different liquid injections (isolated droplet, train of droplets and continuous jet) helps to determine which injection type must be preferred. From that, coating depositions have...
متن کاملMicrostructure of Laser Re-Melted AlCoCrCuFeNi High Entropy Alloy Coatings Produced by Plasma Spraying
An AlCoCrCuFeNi high-entropy alloy (HEA) coating was fabricated on a pure magnesium substrate using a two-step method, involving plasma spray processing and laser re-melting. After laser re-melting, the microporosity present in the as-sprayed coating was eliminated, and a dense surface layer was obtained. The microstructure of the laser-remelted layer exhibits an epitaxial growth of columnar de...
