FUTURE PROJECTS
Frictional Cladding
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.
Applications Invited
Collaboration research and new materials for cladding,Testing
Laser Cladding - Additive Manufacturing
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 Metal Parts
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.

In accordance with the current demand for surface engineering on metals in the present industrial application, we have introduced the surface friction process. In this process, the coating on different metals will occur through the use of friction between two metals. It has some advantages such as resistance to wear and corrosion, durability, energy losses due to friction, etc. This process was to obtain various hard metal coatings, such as aluminum on mild steel coatings. In the process of surface friction, not only because it is cheaper and the properties remain under the base metal coating. The coating on the metal will only take place at the recrystallization temperature of the original metal. So that the base metal does not melt because the structure and properties of the base metal will remain constant. The main concept of this project is to know the properties of the interface of non-ferrous metals after coating on ferrous metals using this surface friction process. The effects of process parameters, the characteristics of the interfacial bond and the mechanical properties of the coatings are studied.

Friction surfacing is a solid-state coating technique process in which a mechtrode is rotated against the substrate under pressure, henceforth forming a coat on the substrate. This process not only can be used as coating process but it also provides flexibility in coating different materials as a revamp manufacturing process and it is suitable for getting excellent mechanical properties after the surfaced deposits. Bond strength is very good and these deposits are expected to serve better service life. The present work deals with mechtrode of SS-316, D3-tool steel and aa-2014 are coated on low carbon steel substrate by friction surfacing process and design of experiment were done by using taguchi L9 orthogonal array where the process parameters are mechtrode, rotational speed and traverse speed. The coating thickness, coating width and the SEM-microstructure analysis were studied.
