Dr. Hélène AGEORGES is an Associate Professor of Renewable Energy and Thermal Spraying at the University of Limoges. Head of Bachelor Program of Renewable Energy. Head of the Master Program of Energy Efficiency and Sustainable Development (Dual Diploma University of Limoges / University of Mascareignes in Mauritius). Researcher in Surface Engineering by Thermal Spray Technologies at the Institute of research for ceramics, France. Her research topics focus on advanced properties of coatings through the use of new materials and innovative processes in fields such as high wear resistance, low friction coefficient, high temperature protective coatings (thermal and environmental barrier coatings), bioactivity (implant coatings), photocatalysis to meet the requirements of various specific applications. She studies nano and micro-structure coating effects, tribology, wear mechanisms. She contributes to the development of new easy and quick methods of mechanical property measurements for industry. Dr. Ageorges also had contributions to the manufacturing of feedstock powders for thermal spray coatings: cermets, composites and bioactive glasses for biomedical use. She holds a PhD in plasma process engineering from the University of Toulouse, France.
