| Abstract: | Supersonic fine particles bombarding (SFPB) is an important means to perform surface nanocrystallization, and the special equipment with excellent features is the key to prepare nanocrystallline surface layer. Consequently, based on the theory of numerical value modeling, the SFPB spraying gun used for surface nanocrystallization is developed, which may produce average bombarding particles velocity of 320 m/s at distance of 50 mm from outlet of the gun. Then, the equipment discussed above is integrated afte... |
