| 中文摘要: |
| 采用熔铸法获得65Cu-3Si-0.1P和65Cu-1Si-0.1P两种新型无铅黄铜,利用金相显微镜(OM)、扫描电子显微镜(SEM)、X射线衍射仪(XRD)对其进行物相分析,通过腐蚀试验、拉伸试验、切削试验评价其综合性能.结果表明同时加入Si、P元素后合金中产生大量细小硬质点,可以起到类似铅黄铜中铅质点的作用,从而改善切削加工性能;Si和P的加入亦可大大提高黄铜的耐腐蚀性能. |
| 英文摘要: |
| 65Cu-3Si-0.1P and 65Cu-1Si-0.1P lead-free brass were obtained through casting method.The microstructures of new alloys were analyzed by OM,SEM,XRD,and the comprehensive properties were evaluated through the tensile test,corrosion test and cutting test.The results show that many hard spots were generated as a result of the addition of Si and P,and these hard spots improved the machining performance as the lead particles do in the ordinary brass.The anti-corrosion performance can also be significantly improved under the same condition. |
