摘要
为了研究激光冲击处理对AZ31B镁合金表面质量的影响,采用波长1 064 nm、脉冲宽度15 ns、脉冲能量10 J、光斑直径3mm的钕玻璃脉冲激光器,对轧制态AZ31B镁合金薄板试样表面进行激光冲击处理。试验结果表明:单次冲击所形成的凹坑深度达到39.122μm;由于激光能量分布不均匀,导致AZ31B镁合金表面粗糙度值增大。
In order to determine the effect of magnesium alloy, AZ31B magnesium alloy sheets laser shock processing on surface quality of AZ31B surface were processed with Nd： YAG laser, laser wavelength 1064 nm, pulse width 15 ns, pulse energy 10 J, spot diameter 3 mm. Test results show that the depth of pit by single laser impact is at 39. 122μm, uneven distribution of the laser energy leads to AZ31B magnesium alloy surface roughness increasing.
