Prof. Xiaofeng Wan is currently working as an associate professor at the School of Mechanical Engineering, Nantong University (Nantong, China). He obtained his M.S. and Ph.D. from Southeast University in 2005 and 2010, respectively. From 2018 to 2019, he was a visiting scholar at the School of Engineering of the University of Alberta, Canada. He conducts theoretical and applied research on component remanufacturing and surface processing based on additive repair technology, including the following: (1) research on the optimization of laser processing alloy coating process and coating tribology, selecting typical metal composite coatings as the main research objects to provide basic data and theoretical guidance for the application of structural and functional coatings such as wear resistance and corrosion resistance; (2) the development of matching surface protection technologies and coating manufacturing processes, such as cold (hot) spraying and chemical heat treatment to give parts high-temperature resistance, corrosion resistance, wear resistance, fatigue resistance and other properties, to extend the service life of components and high-reliability service.
