About

Dr. G. Padmanabham is a distinguished researcher in advanced manufacturing and materials processing, with a primary focus on laser-based surface engineering and repair technologies. His major contributions lie in the development of laser cladding and surface hardening techniques for high-performance industrial components. Notably, his work on laser cladding of ultra-high strength AerMet-100 alloy powder onto AISI-4340 steel has provided a groundbreaking method for the repair and refurbishment of critical aerospace and defense components, a study that has garnered 23 citations for its practical significance. Dr. Padmanabham also made impactful strides in the automotive sector, where he systematically investigated laser surface hardening of crankshafts using a diode laser integrated with a 6-axis robot. This work enabled the effective, industry-ready implementation of laser hardening to improve wear resistance and component longevity. Through these efforts, he has bridged the gap between advanced laser processing research and real-world industrial application, establishing himself as a key figure in the field of laser materials processing.
