This book details the relationships between microstructure, interface roughness, and properties of thermal barrier coatings. The author proposes a method for the reduction of the thermal conductivity of the ceramic layer in order to increase the lifetime of thermal barrier coatings. He includes models for the optimization of ceramic layer microstructure and interface roughness.
Mohit comes from Lucknow in India and received his bachelor's degree in mechanical engineering in 2009 from Indian Institute of Technology Kanpur, India. He received his master's degree in mechanical engineering in 2010 and doctoral degree in production technology in 2015 from University West, Sweden. He is currently employed as a seni...
