| 中文摘要: |
| 采用磁控溅射真空镀膜技术制备银包铝复合线坯，通过后续不退火多道次拉拔，制备低密度的超细银包铝复合软导线。结果表明，磁控溅射处理时，银镀层厚度随走线速度加快而变薄，随溅射电流增加而增厚；拉拔加工要求银镀膜层厚度大于1.3 μm，道次变形量宜小于7%；随银镀层厚度增加，制备的10 μm超细丝的密度和抗拉强度均增大。将φ15 μm的纯铝芯材采用优选条件溅射镀银膜，经拉拔加工制得φ10 μm的银包铝复合软导线，其密度为4.87 g/cm3，抗拉强度286 MPa，复层表面均匀致密无缺陷。 |
| 英文摘要: |
| Composite wire billets of silver clad aluminum was prepared using a vacuum magnetron sputtering coating system, and the low-density and ultrafine sliver clad aluminum composite flexible wire was formed by multi-pass drawing without annealing. The results showed that the thickness of Ag coating became thinner as the wiring speed increasing during magnetron sputtering, and increased with the sputtering current. The drawing process requires that the thickness of silver coating layer is greater than 1.3 μm and the pass reduction should be less than 7%. Both density and tensile strength increased with the Ag-coat thickness of ultrafine wire. A pure aluminum core material with a diameter of 15 μm was sputtered with Ag coating under optimum sputtering condition, and a silver clad aluminum flexible wire with a diameter of 10 μm was prepared by drawing process. Its density was 4.87 g/cm3 and tensile strength was 286 MPa, and its coating surface was uniform and dense without defects. |
