摘要
铍青铜作为一种新型高科技特种合金材料,被广泛应用于制作高级弹性元件和电子元件,已逐步发展成为一种不可或缺的工业材料,但由于铍青铜材料的硬度高,耐磨性好,粘附性强,导致其加工性能差,属于典型的难加工材料,因此研究易切削加工的铍青铜材料替代普通的铍青铜材料具有重要的意义。通过开展拉伸试验、导电率测试、切削试验、机械寿命试验,对易切削铍青铜TBe1.9-0.4和普通铍青铜TBe2的化学成分、力学性能、电性能、疲劳性能等指标进行对比研究,发现2种材料的理化性能、疲劳性能等指标接近。深入分析2种材料经切削加工试验后的切削屑形貌和加工零件的表面粗糙度,证明了TBe1.9-0.4具有优异的切削加工性能。TBe1.9-0.4可作为一种易切削的弹性材料应用于电子元器件行业中。
As a new type of high-tech special alloy material,beryllium bronze has been widely used in the production of advanced elastic components and electronic components and it has gradually developed into an indispensable industrial material.However,due to the high hardness,wear resistance and the strong adhesion of beryllium bronze materials,these resulted in poor processing performance of beryllium bronze materials,so it was a typical difficult-to-machine material.Therefore,it was of great significance to study the beryllium bronze material that was easy to cut and replace the ordinary beryllium bronze materials.By carrying out tensile test,electrical conductivity test,cutting test,mechanical life test,the chemical composition,mechanical properties,electrical properties,fatigue properties and other indicators of free-cutting beryllium bronze TBe1.9-0.4 and ordinary beryllium bronze TBe2 were compared and researched.It was found that the physical and chemical properties,fatigue properties and other indicators of the two materials were close.The in-depth analysis of the chip morphology and the surface roughness of the machined parts of the two materials after the cutting test proved that TBe1.9-0.4 had excellent cutting performance.TBe1.9-0.4 could be used in the electronic components industry as a free-cutting elastic material.
