Formation 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...
متن کاملIn situ Particle Generation and Splat Formation During Solution Precursor Plasma Spraying of YttriaStabilized Zirconia Coatings
Thermal barrier coatings (TBCs) based on Yttria-stabilized Zirconia (YSZ) deposited by the solution precursor plasma spray (SPPS) technique have been claimed to exhibit superior durability compared to conventional plasma spraying and even electron-beam physical vapor deposition. This has been attributed to the interesting features, like vertical cracks, nanosized pores, and fine splats that are...
متن کاملSuspension Plasma Sprayed Titanium Oxide and Hydroxyapatite Coatings
The paper aims at development of TiO2, Ca5(PO4)3OH (hydroxyapatite, HA) and their multilayer coatings onto stainless steel, titanium and aluminum substrate using suspension plasma spraying. The total thickness of the coatings was in the range 10 to 150 μm. The suspension on the base of distilled water, ethanol and their mixtures was formulated with the use of fine commercial TiO2 pigment crysta...
متن کاملSplat Formation and Nanohardness Investigation of Atmospheric Plasma Sprayed Alumina
Atmospheric plasma spraying (APS) is a well established process for preparing ceramic coatings. In this process, powder particles injected into the plasma jet are heated and accelerated simultaneously in the plasma stream and are deposited in molten or semi-molten droplets conditions onto a prepared substrate. During droplet impingement, these molten droplets rapidly solidify to form single spl...
متن کاملSolid Particle Erosion of Thermal Sprayed Coatings
Solid particle erosion is an important material degradation mechanism. Although various methods of coating are tried and used for protection against erosion, thermal sprayed coating for such purpose is the most widely used method. In this chapter, evolution of thermal sprayed coating, erosion testing methods, and erosive wear of thermal sprayed coatings are discussed extensively with emphasis o...
