[0002] In actual use, unmanned aerial vehicles are exposed to various environments containing salt, such as work at the seaside and flight in an atmospheric environment containing salt. These harsh environments are simulated by a salt mist box to test the corrosion resistance of metal spare parts (such as motor housings and landing gears) and some non-metal spare parts (such as the coating of composite material housings) of the unmanned aerial vehicle. The quality and service life of the spare parts are evaluated by observing the corrosion degree of the spare parts in the salt mist environment, such as whether rust spots and material peeling occur.
