This paper aimed to study the influence of blast furnace slags on mechanical, thermal and tribological properties of friction materials elaborated by the dry heat-pressmolding method. Physical, mechanical and thermal properties were analyzed and tribological behavior was studied for varying the extent of doping (13-43 wt.%). The results indicate that the hardness decreases from 63.6 HRL to 57.0 HRL with increasing slag content from 0 to 43 wt. %. But density is opposite for the doped samples. The impact strength gradually increases from 3.59 kJ/m(2) to 3.70 kJ/m(2) when the content of slag increases from 0 to 43 wt.%. Doping was also found to increase the friction coefficients but decrease wear rates, mass-loss and heat release. The sample S-4 has a more superior and stable friction coefficient than others because of the transfer layers formed on the surface of friction materials. (C) 2015 Elsevier Ltd. All rights reserved.
