【摘要】 使用装备了可编程序控制器的电子束焊接设备,研究新型铝基复合材料TiB2/ZL101的焊接性。在合适的工艺参数和扫描频率下,通过电子束焊接方法可以得到无缺陷的焊缝,焊后增强相TiB2在焊缝中分布均匀,未出现偏析现象。对焊缝进行拉伸性能测试,均在母材处发生断裂,电子束焊接得到了较高的焊缝强度;通过对焊缝进行磨损测试,焊缝的抗磨损性能得到了显著的提升。研究表明,采用电子束焊接方法可以有效地完成新型铝及复合材料TiB2/ZL101的焊接。更多还原

【Abstract】 The welding property of TiB2/ZL101 composite was investigated using electron beam(EB) welding experimental system with a function generator.The fine defect-free welding seam was obtained under proper processing parameters and scanning rate.The reinforcement particles TiB2 distributed homogeneously in welding seam without any segregation.The tensile results show that fracture occurs at the base metal and elastic modulus increases compared with base metal.Wear resistance of welding seam is improved greatly compared with base metal.The results show that the TiB2/ZL101 composite can be successfully welded by EB technology.更多还原
