In the initial state, the rotating assembly 3 is in an open state. Place the aluminum casting to be cold sprayed inside the inner sides of two adjacent L-shaped placing hooks 306 at the same horizontal position. Then, start the forward and reverse motor 201 through the control terminal 104. The first rotating shaft 202 rotates following the output end of the forward and reverse motor 201. The first rotating shaft 202 drives the connecting plate 203, the U-shaped frame 204, and the transparent observation window 205 to rotate, so that the space for placing the aluminum casting is blocked by the U-shaped frame 204 and the transparent observation window 205 and is in a closed state. This design effectively prevents the aluminum casting from being sprayed outside the platform during cold spraying operation. Start the motor 302 and the cold spraying equipment main body 401 through the control terminal 104. The output end of the motor 302 drives the second rotating shaft 303 to rotate slowly. The connecting rod 305, the L-shaped placing hook 306, and the bottom plate 304 rotate slowly following the second rotating shaft 303. At the same time, the cold spraying equipment main body 401 shoots the coating powder through the output main pipe 402, the one-to-four branch pipe 403, the output branch pipe 404, and the nozzle 405 by the supersonic gas-solid two-phase airflow onto the surface of the rotating aluminum casting to form a dense coating.
