| 中文摘要: |
| 采用石膏模精密浇注工艺技术，成功制备了银稀土合金铸锭，并确定了合理的浇注工艺技术参数，分析了稀土元素的作用机理。结果表明，在银中添加多元稀土元素(La、Ce、Sm、Y)，改善了银合金的物理、力学、焊接性能、抗氧化和耐腐蚀性能。研发的新型银多元稀土合金具有良好的抗氧化、耐腐蚀性能及可铸性能，在银饰品材料领域具有明显的应用市场前景。 |
| 英文摘要: |
| 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. |
