I am actively involved in research and development in metal additive manufacturing, laser cladding, and laser-selective surface hardening of alloy components. My work combines innovative engineering approaches and systematic experimental investigations, contributing to scientific advancements and industrial-scale demonstrations in additive manufacturing, laser surface engineering, and sol-gel coating technologies.
In 2017, I played a key role in establishing the Joint Technical Demonstration Centre for Additive Manufacturing in collaboration with SLM Solutions at ARCI, Hyderabad, India. My expertise spans the full spectrum of additive manufacturing processes, including Laser Powder Bed Fusion (LPBF), design for additive manufacturing (DFAM), powder characterization, post-processing, and mechanical and metallurgical property evaluation.
Key Contributions:
- Development of DFAM solutions for conformal cooling channels in H13 PDC core pins and stainless steel plates (2 mm thick with 0.4 mm channels). Additive manufacturing, testing, and validation of designed core pins in industrial applications.
- Creation of advanced co-axial powder feeding nozzles with conformal cooling channels for Directed Energy Deposition (DED).
- Innovations in bi-metallic and hybrid additive manufacturing (e.g., Cu-SS, SS-Inconel, H13-H13).
- Design and fabrication of thin-walled AM components (0.3–0.4 mm wall thickness).
Specialized Expertise:
- Additive Manufacturing Processes: Pre-processing, DFAM, process parameter optimization, powder handling, and post-processing.
- Characterization Techniques: SEM/FESEM, TEM, XRD, EBSD, tensile and micro-tensile testing, residual stress measurement, and tribological studies (fretting wear, sliding wear, abrasion, and erosion).
Through my work, I aim to advance the frontiers of additive manufacturing and materials science, delivering innovative solutions for industrial and scientific applications.
