Polytechnique Montréal, Canada
Jolanta Klemberg-Sapieha, JEKS is Professor at Polytechnique Montréal. The main research interests of JEKS are the science and technology of thin films, surfaces, interfaces, and coating systems. She has particularly contributed to the field of hard and super hard protective coatings, tribological coatings, mechanical and tribo-corrosion properties of materials, coatings on plastics, and surface and interface analysis in the context of aerospace, manufacturing, bio-medical, optical, automotive, and other applications.In 2022 she won the prestigious Bunshah Award of the Advanced Surface Engineering Division of AVS for her seminal contribution to “the development of multifunctional and protective nanostructured coatings with tailored mechanical properties for aerospace, manufacturing, and other advanced applications.’’ Her research resulted in more than 350 publications and 13 patents. 

Talk title: Functional Coatings for Aerospace Application
Materials exposed to demanding environments in applications such as aerospace continue to face increased technological, environmental and economic challenges, especially since the performance of systems and components is frequently pushed to and beyond their limits. This is particularly valid for aircraft engine parts exposed to harsh operation conditions that can vary widely from severe erosive wear to exposure to hot oxidative gases, extreme thermal loads, corrosion, or even instant ice accretion on critical surfaces leading to material deterioration that gives rise to increased operation and maintenance costs, decreased efficiency, premature failure, and compromised safety. This calls for a better understanding of the material deterioration mechanisms and for developing appropriate strategies to protect technologically relevant substrate materials and their surfaces.
