Abstract:
1. A method of fabricating a disk for a disk brake system, comprising: (a) forming a cladding workpiece having a first major external surface defining engagement features, which include beads arranged with groups of beads in mutual contact, to increase rigidity of said cladding workpiece; (b) coating said first major external surface with a second metal; (c) providing a mold, defining an interior shape of a rotor; (d) inserting said cladding workpiece into said mold; (e) providing a molten third metal; and (f) pouring said molten third metal into said mold so that it engages to said engagement features and reacts with said second metal and permitting said molten third metal to cool, thereby forming a disk made in part of said third metal, which is metallurgically bonded and mechanically interlocked to said cladding workpiece, together forming a complete disk.
