| Abstract: | By adopting plaster mold casting technology, the silver alloy ingot were successfully casted, and the reasonable casting technology parameters were determined, and the function mechanism of rare earth elements was analyzed. The results showed that, by adding multiple rare earth elements (La, Ce, Sm, Y) in the silver, effectively improved the physical, mechanical, welding performance, oxidation resistance and corrosion resistance properties of alloy. The silver alloy has good oxidation resistance and corrosion resistance properties and discoloration resistance. The casting performance of silver multiple rare earth alloy is good, can satisfy the requirement of jewelry casting. |
