Abstract: By using bibliometrics and visual analysis tools, this paper introduces the research situation of biodegradable metal materials, and provides reference for the development of biodegradable metal materials. Based on the Scopus database, the retrieval time is up to 2018: firstly, from a macro perspective, statistical analysis of academic outputs and development trends, as well as the distribution of literature types; secondly, relevant literatures from 2014 to 2018 were selected to analyze the citation times of top 10 countries, top 10 institutions and top 10 scholars; then, CiteSpace.5.5.R2 was used to analyze the authors' and institutions' cooperation networks on the relevant literatures published in 2014—2018; finally, Scival was used to analyze the key words of relevant literatures published in 2014—2018. In the past five years (2014—2018), the most cited country is China, the most cited institution is Peking University, and the most cited scholars is Zheng Yufeng of Peking University. The research team with Zheng Yufeng from Peking University and other scholars as the core constitutes the largest author cooperation subnet; the research team with Peking University as the core and the research team with Chinese Academy of Sciences as the core constitute two relatively large institution cooperation subnets. At present, many biodegradable metal materials are studied, such as magnesium, magnesium alloy, titanium, titanium alloy, etc.; three properties of biodegradable metal materials are studied: biocompatibility, degradability/corrosion resistance, mechanical properties; biodegradable metal materials are mainly used in medical aspects, such as bone repair, tooth repair, stent, etc. As a research field in the development stage, the best state of biocompatibility, degradability/corrosion resistance, mechanical properties is the focus and direction of the research, which is the judgment standard of whether biodegradable metal materials are suitable for implantation into human body.
