By Dr. D K Dwivedi   |   IIT Roorkee
Learners enrolled: 744
The course content is designed to have systematic and comprehensive understanding on various aspects related with surface engineering of metallic components for enhanced tribological life. It is proposed to include fundamental mechanisms of wear such as adhesive, abrasive, erosive, cavitation, corrosion etc., governing laws, materials properties importance for improved wear resistance under different wear conditions, materials increased tribological life, processes for engineering surfaces of three board categories a) regulating the micro-structure without changing chemical composition b) modification of chemical composition of near surface layers and c) developing of films, coating, and cladding on the. Methods of characterization needed for evaluating the metallurgical and mechanical and tribological properties and performance of engineered surfaces shall also be presented. Presentations will be supported with case studies for effective communication of concepts and procedures. Case studies will be taken up regarding surface engineering of various metal systems like ferrous and non-ferrous metals using different approaches discussed

Instructor bio


Dr. D K Dwivedi obtained BE (mechanical engineering) , in 1993 from GEC Rewa, ME (welding engineering) from Univ. of Roorkee in 1997 and PhD in Met. Engineering from MNIT, Jaipur in 2003. He has about 9 years teaching experience at NIT Hamirpur and 12 years at IIT Roorkee of subjects related with manufacturing at UG level and welding engineering related subjects at PG level including failure analysis of welded joints. He has undertaken work of failure investigation valves, penstocks, bridges for many private and public sector industries especially in hydropower sector. He has published more than 100 research papers in SCI/SCIE indexed journals and undertaken 16 sponsored research and 50 industrial consultancy projects. Instructor has authored two books entitled Production and Properties of Cast Al-Si Alloys with New Age International, New Delhi (2013) and Surface Engineering with Springer, New Delhi (2018).
