Vibration coating process in microgravity environment

The invention discloses a vibration coating process in a microgravity environment, which comprises the following steps: immersing a product covered with a coating in a microgravity liquid, driving a base to apply an external force to the product covered with the coating to generate vibration through the work of a vibrator mounted on a platform base, and adjusting the frequency, amplitude and direction of the vibration so as to realize the vibration coating of the product covered with the coating. The redundant coating is thrown away from the product and settles to a recycling pool at the bottom layer of the microgravity liquid to be recycled; and meanwhile, the coating is uniformly and fully distributed in and (or) on the outer surface of the product, especially on all corners and gaps with narrow spaces. And vibration can be generated through an external vibration generator, so that the microgravity liquid is driven to vibrate, and the coating is more uniform, complete and compact by changing the vibration f
