Frictional cladding is a solid-state process used to apply a coating or repair surfaces by using frictional heat. A rotating consumable tool is pressed against a substrate, generating heat that softens the material without melting it. The softened material is then deposited onto the substrate, forming a strong bond. This method is used for surface protection, repairing worn components, and joining dissimilar materials, especially in applications requiring wear, corrosion, or thermal resistance.
Laser cladding is a surface engineering technique with significant research interest due to its ability to create high-performance coatings. The process involves using a focused laser to fuse cladding material onto a substrate, improving wear, corrosion, and heat resistance. Research areas include optimizing process parameters, developing new cladding materials (e.g., metal matrix composites), and enhancing the understanding of microstructural evolution and bonding mechanisms. Technology is crucial in the aerospace, automotive, and energy sectors to extend the life of critical components.
Post-finishing of additive manufacturing (AM) metal parts is a critical research area aimed at improving surface finish, mechanical properties, and dimensional accuracy. Key techniques under study include machining, heat treatment, surface finishing, and Hot Isostatic Pressing (HIP). Research is focused on optimizing these processes, developing hybrid methods, and integrating automation to enhance efficiency, reduce costs, and meet industry-specific requirements, especially in aerospace and medical applications.
