Non-linear elastic properties of plasma-sprayed zirconia coatings and associated relationships with processing conditions
Low-temperature thermal cycling of plasma-sprayed zirconia coatings via curvature measurements revealed their in-plane non-linear behavior. This feature arises from the unique layered, porous and cracked morphology of thermal-sprayed ceramic materials. The nonlinear aspect can be quantified by a novel data interpretation procedure consisting of modified beam bending analysis and inverse analysi...
متن کاملEffects of pores and interfaces on effective properties of plasma sprayed zirconia coatings
It is difficult to establish structure–property relationships in plasma sprayed coatings because of their unique and intermingled splat microstructures incorporating networks of various intrinsic process-dependent microdefects. In this paper, these coatings are characterized using two distinctly different approaches, both based on novel experimental techniques and computational modeling tools. ...
متن کاملMicrostructure formation in plasma-sprayed functionally graded NiCoCrAlY/yttria-stabilized zirconia coatings
Functionally graded NiCoCrAlY/yttria-stabilized zirconia coatings were fabricated by plasma spraying using mechanically alloyed, plasma-spheroidized NiCoCrAlY/yttria-stabilized zirconia (YSZ) composite powders. Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS) analysis revealed that oxidation of aluminum, chromium and yttrium in the NiCoCrAlY alloy occurred in th...
متن کاملMicrostructure and Properties of Plasma Sprayed Nanostructural ZrO2 Coatings
Plasma sprayed zirconia deposits have been employed in wide applications for thermal protection. Recently, the use of nanostructural surface represents an alternative for improving the performance of these coatings. The present paper reviewed the works in this field at our research group, including synthesis of nanostructural ZrO2 powders, influence of spraying parameters on microstructure and ...
