Title:
SILICON CARBIDE-REINFORCED STIBIUM-STANNUM-COPPER ALLOY BAR AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/107847
Kind Code:
A1
Abstract:
A silicon carbide-reinforced stibium-stannum-copper alloy bar for high speed locomotive gears and a manufacturing method therefor. The alloy bar consists of the following components in percentage by weight: silicon carbide (SiC) 0.5-1.5%, stannum (Sn) 6-7.5%, stibium (Sb) 2-3%, lanthanum (La) and cerium (Ce) 0.1-0.5%, and the balance of copper. The method comprises fusing a non-metallic material (silicon carbide) and metallic materials (copper, stibium, and stannum) to prepare a composite material by means of a particular process of smelting, stirring, and casting. Both the hardness and wear resistance of the composite material are superior to those of a conventional leaded stannum bronze alloy, thereby further meeting requirements of specialized gears of a high speed locomotive.
