The company has developed a kind of tooth-shaped cushion for protecting magnesium alloy wheel hub and its processing technology. In order to solve the technological and technical problems existing in the electric corrosion protection of magnesium alloy wheels, the formed boss tooth-shaped pad and the outer wall of the holes on the wheels are inlaid with micro-shaped teeth, which are treated by micro-arc oxidation surface to become an insulator, insert into the pre-insert hole of the central locating hole or bolt connecting hole of the micro-arc oxidation treated magnesium alloy wheel hub; when the wheel locating shaft and hub connecting bolt are screwed into the hole, there is no potential difference between aluminum alloy and magnesium alloy wheel after micro-arc oxidation, which eliminates the electrochemical corrosion caused by potential difference After the micro-teeth of the tooth-shaped cushion are closely occluded with the center locating hole and the inner tooth surface of the pre-set Hole, the slip phenomenon is eliminated and the torsion strength of the tooth-shaped cushion is increased.
