Carbon-Fiber Reinforced Glass Ceramic Coatings
Co-Supervisor: Nurullah Çöpoğlu, Assoc Prof. Dr. Buğra Çiçek
Glass-ceramic coatings (GCCs) are generated by the controlled heat-treatment process of a parent system on ferrous or non-ferrous substrates by wet or dry coating techniques [1], [2]. Glass-ceramics provide high-temperature and abrasion resistance, high strength, machinability, and biocompatibility by integrating the characteristics of glasses with the advantages of crystalline phases [3], [4]. Glass-ceramic coatings possess low abrasion resistance due to their brittleness nature, in contrast to their strong technical characteristics [5]. A combination of high hardness and toughness can enhance this resistance. Therefore, the goal of this study is to enhance the toughness of these high-hardness coatings by incorporating high-hardness and modular carbon fiber. Carbon fiber reinforced glass matrix composites have a variety of properties, including high strength, stiffness, excellent toughness, low density, and unique tribological behavior for structural applications [6]. The main disadvantage of this type of composite is its low oxidation resistance in an oxidative atmosphere at high temperatures. During the fracture of the coatings containing carbon fiber, when a crack reaches the carbon fibers, debonding and pull-out occur, and hence the strain energy release rate for the toughness mechanism increases. With significant fiber pull-out, the composite fracture strain is greater than that of the coating alone, indicating improved composite toughness [7].
