The material of the connecting bolt in a certain product of the red flag is aluminum alloy, the shell body for connection is also made of aluminum alloy, and the bolt made of the material cannot be easily corroded under normal conditions. However, aluminum alloy bolts after the snow melt agent corrosion resistance test cause bolt fracture during the bench test. The corrosion of the snow-melting agent used in the test is more serious than that of the traditional sodium chloride if calcium salt or magnesium salt is used.
After the connection assembly of the corroded bolt, corrosion media permeate into the threaded hole to cause corrosion of the thread and the threaded hole, and after the threaded hole is corroded, the pretightening force of the thread is reduced, so that the fatigue fracture of the bolt can be caused under the long-term fatigue load action.
