Abstract

PURPOSE:To improve the extent of abrasion resistance by manufacturing a disk brake rotor with cast iron made up of dispersing ZrSiO4 or the like to be mixed in a disk brake pad in an Fe-C structure. CONSTITUTION:Cast iron of Fe-3.3(wt.%)C is melted and cooled as being stirred up and it is kept somewhere about 1200 degrees. A globular grain of ZrSiO4 of 7 in Mohs' hardness and about 20mum in grain size just the same as those mixed in pad material is put in molten metal as much as about 3%wt. and, after being stirred up until it comes to uniformity, molded and thus a disk brake rotor consisting of such a material that has a structure made up of dispersing spheroidal graphite 2 and hard grains 3 in pearlite 1 is manufactured. Since the hard grains are dispersed in the cast iron of the rotor, abrasion resistance is improved.
