Dr. Amit Mahajan is Associate Professor at Khalsa College of Engineering & Technology, Amritsar, India. His research interests include additive manufacturing, surface modification of biomaterials, and electrical discharge machining. In his Ph.D., he profitably fabricated the nano-structured bio-favorable coatings on metallic biomaterials using powder mixed electrical discharge machining technique. His research aimed to design the carbon nanotubes (CNTs) and μ-hydroxyapatite (μHAp) mixed coatings on β-type titanium alloy. He investigated the biological responses in terms of hydrophobicity and hydrophilicity tribological properties, corrosion inertness, bioactivity, etc. Currently, he works on the fabrication of alloys with proper fraction composition of carbon nanotubes (CNTs) and μ-hydroxyapatite (μHAp) via additive manufacturing. He has contributed 23 research papers and chapters to leading international journals, books, and conferences. He also serves as Reviewer for several national and international journals of repute. Dr. Sandeep Devgan is Associate Professor at Khalsa College of Engineering & Technology, Amritsar, India.
