company news about Why protect the boss toothed pads of magnesium alloy wheel hubs?

The company has developed a boss toothed pad to protect the hub of magnesium alloy wheels. Solve the technical and technical problems in the protection of magnesium alloy wheel hubs from electrical corrosion. It becomes an insulator and is inserted into the center positioning hole or the pre-inserted hole of the bolt connection hole of the magnesium alloy wheel hub that has undergone micro-arc oxidation treatment. When the wheel alignment shaft and the wheel hub connecting bolt are screwed into it, the joint surface of the screw-in part contacts the aluminum alloy toothed pad after micro-arc oxidation, and there is no potential difference with the magnesium alloy wheel hub, which eliminates the potential difference caused by electrochemistry. Corrosion; after the micro-shaped teeth of the boss toothed pad are tightly engaged with the central positioning hole and the toothed surface of the inner wall of the pre-inserted hole, the slippage phenomenon is eliminated and the torsional strength of the boss toothed pad is increased.
