  • About author:Prof. Rong-Chang Zeng obtained his Ph.D degree at the Institute of Metals Research, Chinese Academy of Sciences in August 2003. During July 2003-Jun. 2010, he worked in Chongqing University of Technology, China. From March 2006 to February 2007, Dr. Zeng studied in Helmholtz- Zentrum Geesthacht (HZG) in Germany as a visiting scientist. Since June 2010, Prof. Zeng has been employed as a professor by Shandong University of Science and Technology, China, and the head of research group “Corrosion and Protection of Materials” and corrosion laboratory for light metals. Prof. Zeng is the member of the editorial boards or guest editor of seven peer-reviewed journals, i.e., Journal of Magnesium and Alloys, Frontier of Materials Science and Heliyon, and peer reviewer of more than 40 journals. He became 2019 Publons Top reviewers in Materials Science and Cross-Field. He has authored/coauthored 150+SCI papers, six books/book chapters and 30 patents. He is an adjunct Professor at Xi’an Jiaotong University (2017-Present) and Wuhan University of Technology (2018-present), and a member of China Magnesium Association (CMA) (2003-Present), council member of Chinese Society for Corrosion and Protection (CSCP) (2017-Present), Chinese Committee for Magnesium and its Application (CCMA) (2015-Present), Committee for Metallic Branch of Chinese society of biomaterials (2014-Present) and Vice-Chairman for Shandong Province Society for Corrosion and Protection (2018-Present). His current interest is focused on corrosion and functional surface modification of biodegradable magnesium alloys.

Abstract:

Magnesium (Mg) alloys as a bioabsorbable light metal have shown great clinical potential as bone replacement implants. In this review, the categories, progress in cutting-edge preparation technologies and antibacterial mechanisms of Mg alloys and considerable numbers of corrosion-resistant and functional coatings are summarized. The relationship among the microstructure (grain size, intermetallic compounds), biocorrosion resistance and biocompatibility for antibacterial Mg alloys is discussed. The challenge and outlooks of biomedical Mg alloys and coatings are proposed from an antibacterial perspective.
