A Study of the Disc Scoring Generation Principle and Reduction(II) 2018-01-1891
In the latest paper, we presented our work based on experiments to study MPU (Metal Pick Up) of the pad and the scoring(scratching) of the disc. The main component of MPU was “Fe”, and if the roughness of the disc was small, the content of “Fe” was increasing, especially in initial condition and the segregation of that was decreasing. In this paper, we give our extensive work about the results by the additional factors i.e. the location of the roughness of disc, the brake pad friction coefficients, and the disc slots. We made the various discs which had the different roughness boundaries and slots, and the pads which had different pad friction coefficients. We find and believe that our experimental data should serve an useful guideline for reducing MPU of the pad and scoring of the disc
