【 摘 要 】

A magnetic ring of elevator brake was analyzed in this paper. The macroscopic morphology and metallographic microstructure of the elevator brake magnetic ring were investigated based on the optical microscope and scanning electron microscope analysis. The chemical composition of magnetic ring was analyzed. The results showed that the abnormal wear was caused by the Zinc bearing metal.
