| Abstract: | In order to improve and enhance the mechanical and wear-resistant properties of high-aluminum zinc foundry alloy (ZA43), the RE metal-cerium was used in modification of ZA43 alloy.The paper had researched and discussed the influences of RE on mechanical properties and wear-resistant properties of ZA43 systematically. The results shows the as-cast microstructure of ZA43 alloy can be refined and the chemical segregation is diminished in ZA43 alloy by adding RE.The mechanical properties and wear-resistant properties had been improved variously by the increase of RE.When the content of RE reaces to 0.15 %, the mechanical properties is the best. The alloy can take the place of copper alloy as a good substitute. |
