摘要:

进行了硒化锌晶体在传统超精密加工和微激光辅助切削(μ-LAM)的对比实验,分析了μ-LAM时激光功率对表面形貌、表面质量的影响规律,获得了最优工艺参数。为揭示μ-LAM机理,采用变温纳米压痕技术分析了硒化锌的力学性能随温度的变化规律。研究表明,在相同的切削条件下,μ-LAM能够显著改善工件的表面质量,但激光功率过大会导致表面质量的恶化,在最优激光功率2.34 W下,可获得最优表面质量,其表面粗糙度为3.97 nm;硒化锌的硬度和弹性模量随着温度的升高而降低,最终改善了材料塑性。

Abstract:

Comparative experiments between μ-LAM and traditional ultra-precision machining were carried out. The effect of laser power of μ-LAM on surface morphology and surface quality was analyzed, and the optimal machining parameters were obtained. To reveal the mechanism of μ-LAM, variable-temperature nanoindentation technique was employed, and temperature-dependent mechanical properties were investigated. Under the same cutting conditions, the results show that the surface quality is improved significantly with μ-LAM. However, excessive laser power may lead to deterioration of surface quality. The best surface quality with surface roughness of 3.97 nm is realized at a laser power of 2.34 W. The hardness and elastic modulus of ZnSe crystal decrease with increasing temperature, resulting in an increase in plasticity.

Key words: ZnSe crystal, micro laser-assisted machining(μ-LAM), Raman spectrum, surface quality, laser power
