A review of the development of surface burnishing process technique based on bibliometric analysis and visualization

Abstract

The surface burnishing process (SBP), by which the surface layer with high hardness, residual compressive pressure, and nanocrystalline structure are obtained, is a practical approach to enhance the metal/alloy surface. The present paper collects a data set in the SBP field from 1990 to 2020 through the Science Citation Index Expanded (Web of Science Core Collection) database to identify and describe the research history, hotspots, and frontiers based on bibliometric analysis and visualization. Firstly, the temporal and spatial distribution of publications are summarized, and the corresponding countries, institutions, journals, and influential authors are also described. Secondly, the keystone publications are identified and analyzed based on a citation network. Thirdly, cluster analysis representing a hot research region field is carried out for all keywords. Finally, after analyzing the evolution route of the SBP field, the future development direction and trend are discussed. This paper is hopefully to help scholars understanding the research patterns of SBP.
