研究了激光脉冲频率、占空比对激光斑点形貌的影响,以及激光脉冲频率、占空比、激光斑点在轧辊的轴向间距距离等毛化参数对轧辊表面形成纹理结构的影响。对比了光纤激光无序毛化板和电火花毛化板的纹理形貌。研究表明:光纤激光无序毛化技术可以毛化出宏观上纹理结构均匀,微观上纹理结构紊乱的轧辊表面。 The effect of laser pulse frequency and duty cycle on the morphology of the laser spot and the effect of the texturing parameters such as laser pulse frequency, duty cycle and the distance between the laser spots on the roll surface on the texture of the roll surface were studied. The texture of fiber laser disordered hair plate and EDM hair plate were compared. The research shows that fiber laser disordered texturing can be used to texturize the roll surface with macroscopically uniform texture structure and microscopic textured structure.
