Abstract
Ferro- based friction material was fabricated by reaction sintering technology, using Fe and Ti elements containing in vanadium and titanium iron concentrate as main raw materials, adding other ingredient on the basic of composition of ferro-based friction material, synthesis and sintering were accomplished unanimously in vacuum resistance furnace. Thermodynamic of the reduction of vanadium and titanium iron concentrate was calculated and studied, and the mass change of the reduction was studied by TG–DSC. The results show that the reduction temperature of Fe and Ti oxides is above 979 K, in the reduction process of vanadium and titanium iron concentrate, Fe3 O4 is reduced by carbon firstly, and then titanomagnetite and ilmenite are reduced into Fe and Ti oxides, and finally different valent titanium oxides are reduced into TiC.Good interface bonding and compact structure have been got in experimental research by making reasonable process route.
