Rassim Younes is a Professor at the Department of Mechanical Engineering, University of Bejaia (Université Abderrahmane Mira de Bejaia), Algeria. He received his Ph.D. in Mechanical Engineering from the University of Bejaia in 2016, with a dissertation focused on the mechanical and microstructural behavior of ceramic coatings produced by thermal spraying. His teaching activities include courses on the physical and mechanical properties of ceramics, tribology, surface engineering, and materials characterization. Professor Younes is a member of the L2ME Laboratory (Laboratory of Mechanics, Materials and Energetics), where he supervises research on advanced coatings and wear-resistant materials. His research interests cover ceramic materials, thermal spray coatings, tribological behavior, microstructural analysis, and mechanical performance of engineering materials. He has contributed to several national and international conferences and publications in the field of surface engineering and materials science.
