Abstract为了研究激光冲击强化对钛合金性能的影响,采用波长1064nm、脉冲能量0~6J、脉冲宽度6~14ns的YAG脉冲激光器对TC4钛合金试样表面进行冲击强化处理,并对其表面的显微硬度和残余应力进行了试验测试与分析。结果表明,采用脉冲能量6J、脉冲宽度12ns、水约束层厚度1.8mm的激光冲击强化参数,冲击区的表面显微硬度明显增加,比处理前提高约33.5%,冲击区表面存在的残余压应力数值高达-323MPa。试验结果表明,激光冲击强化钛合金的效果明显。
Other AbstractIn order to study the effect of laser peening on the properties of titanium alloy, a TC4titanium alloy sample is processed using YAG laser with the wavelength of 1064 nm, pulse energy of 0~6 J and pulse width of 6~14 ns, and its micro-hardness and residual stress are examined and analyzed. The experimental results show that the satisfying laser peening appearance can be achieved when the pulse energy is 6 J, pulse width is 12 ns and tamping layer thickness of water is 1.8 mm, the surface micro-hardness increases up to 33.5%and the compressive residual stress on the surface of laser shocked area reaches;323 MPa. Laser peening improves the hardness and residual stress of titanium alloy significantly. The experimental results show that the effect of laser peening evidently strengthens the titanium alloy.
