This Brief describes the influence of the different organic chelating agents on the topography, physical properties and phases of SPPS-deposited spinel ferrite splats. The author describes how by using the SPPS process, the coating is produced directly from a solution precursor and how all physical and chemical reactions such as evaporation, decomposition, crystallization and coating formation occur in a single step. The author details not only the innovative approach to liquid feeding, but also focuses on its effects on the spinel ferrite system. The results of experimentation as well as detailed explanations of the experiments are included.

This book focuses on droplets and sprays and their applications. It discusses how droplet level transport is central to a multitude of applications and how droplet level manipulation and control can enhance the efficiency and design of multiphase systems. Droplets and sprays are ubiquitous in a variety of multiphase and multiscale applications in surface patterning, oil recovery, combustion, atomization, spray drying, thermal barrier coating, renewable energy, and electronic cooling, to name but a few. This book provides two levels of details pertaining to such applications. Each chapter delves into a specific application and provides not only an overview but also detailed physical insights into the application mechanism from the point of view of droplets and sprays. All chapters provide a mix of cutting-edge applications, new diagnostic techniques and modern computational methodologies, as well as the fundamental physical mechanism involved in each application. Taken together, the chapters provide a translational perspective on these applications, from basic transport processes to optimization, and from design to implementation using droplets or sprays as fundamental building blocks. Given its breadth of coverage, the book will be of interest to students, researchers, and industry professionals alike.

Thermal barrier coatings (TBCs) are insulating coatings used in gas turbine engines to improve energy efficiency. The current choice of TBC material id est yttria stabilized zirconia (YSZ), is limited to temperatures of less than 1200°C because of (a) undesirable phase transformations and (b) prone to the attacks from calcium-magnesium-aluminum-silicate (CMAS) deposits. In this research, the solution precursor plasma spray (SPPS) was employed for the further development of yttrium aluminum garnet (YAG) coatings previously developed at UConn. Thermal conductivity of SPPS YAG was reduced (0.58 W/mK at 1300 °C) by process modifications to generate microstructures with layered porosity termed inter pass boundaries (IPBs). Improvement in the SPPS process for YAG coatings was achieved by enhancing deposition efficiency and deposition rate (DR) through optimizing spraying parameters and precursor concentration. A highest DR value of 209 g/hour was attained thus cutting the cost by 4X over previously deposited SPPS YAG. A 58% increase in standoff distance was also achieved by employing a cascaded high energy gun. The reactivity of YAG with CMAS was evaluated for the first time using systematic heat treatment of composite powder pellets. Experimental results along with optical basicity theory demonstrate that YAG is less reactive to CMAS than YSZ. Simultaneously, resistance of SPPS YAG TBCs was evaluated through CMAS interaction tests, which demonstrated that YAG performed 2X and 8X better than air plasma spray (APS) YSZ in different tests. The performance of YAG TBCs was enhanced drastically (15X higher than previously tested SPPS YAG) by high prominence of IPBs in the microstructure. It was concluded that IPBs act as secondary channels for CMAS infiltration thereby limiting the infiltration depth and prolonging the life. This is proposed as a novel and alternate CMAS mitigation strategy with relies only on microstructural features. The influence of microstructure on CMAS infiltration was also studied on the highly CMAS resistant gadolinium zirconate (GZO) TBCs deposited by both APS and SPPS process. A strong microstructural influence was observed where APS outperformed SPPS GZO by 10X, arresting CMAS at a depth of 25 microns. In SPPS GZO, crack width of arrest.
