Based on the data of patent applications and paper publications of detonation spraying technology, the development process and current situation of detonation spraying technology are studied and analyzed from four perspectives: trends, technologies, regions and research institutions. The analysis results show that in terms of development trend, China is in a relatively active development period of detonation spraying technology. In terms of technical composition, detonation spraying process and coating preparation method are the main technical fields of detonation spraying technology. In terms of geographical distribution, the leading countries of detonation spraying technology are the United States and Russia, and their technology competition relationship with China is formed. In terms of research institutions, Chinese research institutions still need to strengthen planning and continue to carry out in-depth research on detonation spraying technology. In addition, through the analysis of key patents of detonation spraying technology, it is found that the development of detonation spraying equipment for small inner holes and complex parts, the coupling process research of detonation spraying and other technologies, the modification of detonation spraying coating material and the development and application of detonation spraying on the surface of non-metallic materials will be the potential development directions for the detonation spraying technology. © 2022, Editorial Department of the Journal of Chinese High Technology Letters.
