About

Alfredo Valarezo is a leading figure in the field of thermal spray coatings and materials engineering, with a particular focus on the mechanical behavior of ceramic coatings for high-temperature applications. His research centers on understanding the relationship between deposition parameters and the resulting stress evolution in plasma-sprayed coatings, a critical factor for the durability of thermal barrier systems. His most-cited work, the 2012 study "Effect of Deposition Rate on the Stress Evolution of Plasma-Sprayed Yttria-Stabilized Zirconia," has garnered 23 citations, establishing a foundational understanding of how processing conditions influence residual stresses in yttria-stabilized zirconia (YSZ)—a key material in gas turbine engines and aerospace components. This contribution is vital for optimizing coating performance and lifespan. Valarezo’s work bridges fundamental materials science with practical industrial challenges, making him a respected voice in the thermal spray community. His research continues to inform the design of more resilient coatings, directly impacting energy efficiency and component reliability in extreme environments.
