| Abstract: |
| Cold spray additive manufacturing technology is a solid-state additive manufacturing method that relies on the plastic deformation of powder particles to form bonds. As the additive components has almost no defects such as oxidation, phase transformation, grain growth, cracks, etc. The lower deposition temperature has little effect on the heat of the matrix, and has the advantages of high additive efficiency and the manufacture of large components. It has attracted the attention of many national research teams and is recognized as a powerful and useful additive manufacturing and additive repair technology. In view of the increasing attention of scholars and industry at home and abroad to the cold spraying additive manufacturing technology, this paper attempts to summarize the microstructure and properties of typical cold spraying deposits (Cu, Al, Ti, Ta and other materials) on the basis of describing the cold spraying equipment, with emphasis on the application and new progress of cold spraying additive manufacturing technology in the field of national defense. At the same time, the challenges of cold spraying additive manufacturing technology are also pointed out. |
