| 摘 要： | 采用双金属复合材料加工工艺制备铜铅/钢双金属复合材料,对复合材料金相组织、合金成分和界面处相组成进行分析,测定铜铅型轴瓦双金属复合材料的粘结强度。结果表明,专用钢背材料和铜铅合金复合,复合材料粘结强度σ为150 MPa;用08Al钢作钢背,复合材料粘结强度为85 MPa。不同钢背材料对双金属粘结强度产生不同影响,双金属界面金相组织观察和二次电子像结合能谱分析表明,铅均匀分布,未产生偏析现象,Fe原子和Cu原子互扩散而提高了双金属粘结强度。

| Abstract: | The research studies the bond strength of the bimetallic plates of Cu-Pb steel.The experiments and their analysis show that the bond strength of the Cu-Pb bimetallic plates and the special steel is 105 MPa.And the bond strength of Cu-Pb plate and the 08Al steel is 55 MPa.In addition,the study shows that materials backed with different steel have obvious influence on the bond strength.And bimetallic interface analyses suggest that Pb does not present gravity segregation and the diffusion between Fe and Cu atoms increases the bond strength of bimetallic plates. |
