Experimental Investigation of Semi -metallic Disc Brake Materials
半金属盘式刹车材料的试验研究

An orthogonal experimental design,combining with Chase friction testing was used to obtain a semi-metallic disc brake material formula with less effect of temperature,load and velocity on friction coefficient and wear.The average friction coefficient was 0.444.Experimental results show that black iron oxide,a mild abrasive,affected greatly on the standard deviation of friction coefficient relevant to temperature among the four ingredients.This is because that black iron oxide increased the friction at the l...
