为考察纳秒激光不同工艺参数对微织构硬质合金表面质量的影响,以正交试验法设计微织构硬质合金试验。采用残余应力仪、显微硬度仪对织构后的材料表面进行表征。实验表明,激光频率对残余压应力和显微硬度的影响最大;综合考虑各因素对材料的影响,主次影响顺序为频率、时间、光斑直径、激光能量;采用激光能量200 mJ,光斑直径0.5 mm,频率2 Hz,时间1 s的工艺参数可以获得更好的表面微织构效果。 In order to investigate the influence of different process parameters of nanosecond laser on the surface quality of micro-textured cemented carbide, the micro-textured cemented carbide test was designed by orthogonal test. Residual stress meter and microhardness tester were used to characterize the surface of the textured material. Experiments show that the laser frequency has the greatest effect on residual compressive stress and microhardness. Considering the influence of various factors on the material, the order of primary and secondary influences is frequency, time, spot diameter and laser energy. Laser energy is 200 mJ and spot diameter is 0.5 mm, the frequency of 2 Hz, the time of 1 s process parameters can get better surface micro-texture effect.
