SEAM Seminar

‘Can lasers make metals stronger?’

Dr. Niroj Maharjan – R&D scientist at Advanced Remanufacturing and Technology Centre, Singapore

Chair: Dr. Andrew Ang (Cheif Investigator, SEAM, Swinburne University of Technology)

Lasers have found widespread application in the manufacturing industry. Especially, high power lasers can bring significant changes to the surface properties of metal components.  In this talk, he will share some of his work on the application of lasers to strengthen metal surfaces. Particularly, he will talk about laser shock peening and other laser surface treatments to modify metal surfaces and their applications in the industry.

Dr. Niroj Maharjan is currently working as R&D scientist at Advanced Remanufacturing and Technology Centre (ARTC), a public-private industry consortium under Agency for Science, Technology and Research (A*STAR), Singapore. With more than 7 years of experience in advanced manufacturing, he works closely with both academia and industry partners on translational research projects to address challenges in the aerospace, manufacturing, and energy industries. Dr Maharjan’s area of expertise is laser material processing, mechanical peening, and material characterization. Prior to joining ARTC, he completed his doctorate in mechanical engineering from Nanyang Technological University (NTU), Singapore, where he investigated the laser hardening process for steels. Over the years, he has published more than 15 journal papers and participated in multiple international conferences, industry workshops, and events. He is a Chartered Engineer (MIMechE, UK), a founding member of the International Society for Intelligent Manufacturing (ISfIM) and a member of the Singapore Welding Society (SWS).
