Document Type and Number:
WIPO Patent Application WO/2018/028091
Kind Code:
A1
Abstract:
Disclosed is a preparation method for a copper-based composite material for a mechanical part. The preparation method comprises the following steps: placing, by mass percent, 7% - 8% of antimony, 9% - 11.5% of tin, 4% - 6% of zinc, 1% - 2% of nickel, 0.5% - 1.5% of bismuth and the balance of an electrolytic copper into a 500 kg medium frequency induction furnace, and heating same to 1,200 degrees centigrade to 1,250 degrees centigrade, wherein the smelting time is 2.5-3 hours; and at the same time, using a high-temperature-resistant graphite rod to fully stir a completely melted alloy liquid, and maintaining the temperature at 1100 degrees centigrade after the alloy is completely melted, wherein the time for heat preservation and standing is 30-35 minutes. A titanium carbide material is uniformly distributed in the alloy solution of the electrolytic copper, antimony, tin, zinc, nickel and bismuth by a certain technical means, and by using the high hardness performance of titanium carbide, the performance of the alloy material is further improved. The resulting new composite alloy material has a higher strength and hardness, so that the requirements of applying the material to various mechanical parts are satisfied.
