Method for determination of abrasion resistance of carbon cathode materials at room temperature Original Research Article

Test equipment was designed to study the abrasion of carbon cathode materials by alumina slurry at room temperature. The alumina was suspended in a heavy liquid-sodium polytungstate aqueous solution (SPT). Effects of test time, specimen velocity and solid concentration of the slurry were studied. The wear mechanism is discussed. Various carbon cathode materials are ranked against CS graphite which was used as the standard.
