摘要：The friction tests of the outside and inside walls of elevator brake base were conducted. The friction curves and coefficients were obtained. The friction coefficient was about 0.26~0.29. The microstructure of the elevator brake base before and after friction test was investigated based on the optical microscope and scanning electron microscope analysis.
