Research Interests

FromDecember 2017, Dr. Zhu was assigned as an associate editor of ASME-Journal of Tribology.


Dr. Zhu’s main research interests include interfaces, friction, and wear, mainly applied to problems in mechanical systems, such as the wheel-rail contact system, the tribo-pairs in hydraulic pumps and gears.His New research interests include the tribological performance of parts made by metaladditive manufacturing, develop the relation between tribological performance and electrical energy consumption of materials fabricated by metal additive manufacturing. He pioneered the work of studying the tribological performance of various material produced by selective laser melting under lubricated contacts.


Dr. Zhu has published more than 20 scientific papers in international journals (listed in the end)

He gave more than 10 oral presentations in international conferences, such as World Tribology Congress, Nordtrib, Contact Mechanics, IAVSD, including a state-of-the-art presentation “Tribology in the wheel-rail contact” in 23rd IAVSD Symposium on Dynamics of Vehicles on Roads and Tracks.
