About
Sanjay Sampath is a Distinguished Professor in the Department of Materials Science and Chemical Engineering at Stony Brook University. His research encompasses the fields of thermal spray processing of materials, synthesis and application of multilayered surfaces, and the development of direct write technology for thick film sensors and electronics. His current research involves an integrated strategy combining the science and technology of thermal spray processing, focusing on both fundamental aspects, such as the evolution of microstructures under far from equilibrium conditions, and applied aspects related to industrial coating design, performance, and reliability. Professor Sampath has pioneered mesoscale direct writing technologies based on thermal spray for applications in prototyping and manufacturing of thick film sensor structures, electronics, and mesoscale multifunctional systems. He has held leadership roles as the Director of the NSF Materials Research Science & Engineering Center for Thermal Spray Research and the DARPA Thermal Spray based Direct Writing of Mesoscale Electronics & Sensors Systems. His contributions have been recognized through awards including the SUNY Chancellor's Award for Excellence in Scholarship and Creative Activities, the Alcoa Foundation Research Award, and the Kobe Steel Research Award. He earned his Ph.D. in Materials Science and Engineering from Stony Brook University in 1989 and his B.S. B.Tech. in Metallurgy from the Institute of…

Abstract The current generation of multilayer Si/Yb 2 Si 2 O 7 environmental barrier coatings (EBCs) are temperature limited by the melting point of Si, 1414°C. To investigate higher temperature EBCs, the cyclic steam oxidation of EBCs comprised of a single layer of ytterbium disilicate (YbDS) was compared to multilayered Si/YbDS EBCs, both deposited on SiC substrates using atmospheric plasma spray. After 500 1‐h cycles at 1300°C in 90 vol%H 2 O‐10 vol%air with a gas velocity of 1.5 cm/s, both m…
Evaluating steam oxidation kinetics of environmental barrier coatings
Journal of the American Ceramic Society · 2021 · 52 citations
Abstract Environmental barrier coatings (EBCs) are a commercially proven means of protecting SiC‐based materials in gas turbine environments. However, there are little specific data in the literature on the impact of coatings like Yb 2 Si 2 O 7 on preventing accelerated SiO 2 growth in the presence of H 2 O. Quantification of reduced rates are necessary for evaluating and comparing EBC effectiveness and incorporation of silica growth rates into future EBC lifetime models. In this study, baseline…
Steam oxidation and microstructural evolution of rare earth silicate environmental barrier coatings
Journal of the American Ceramic Society · 2022 · 48 citations
Abstract A primary failure mode for environmental barrier coatings (EBCs) on SiC ceramic matrix composites (CMCs) is the oxidation of the intermediate Si‐bond coating, where the formation of SiO 2 at the bond coating–EBC interface results in debonding and spallation. This work compares the microstructure evolution and steam oxidation kinetics of the Si‐bond coating beneath yttrium/ytterbium disilicate ((Y/Yb)DS) and ytterbium disilicate/monosilicate (YbDS/YbMS) EBCs to better understand the impa…
