Embodiment 1
[0016] refer to figure 1 : Laser processing system for composite micro-texture on the surface of ductile iron materials, which is a processing system with focusing lens, including laser [1], photoelectric shutter [2], beam expander [3], mirror [4], computer control system [5], focusing lens [6], CCD [7], workpiece [8], stage [9] and fixture [10]. The computer control system [5] is connected to the laser [1], photoelectric shutter [2], CCD [7] and displacement stage [9] through lines respectively.
[0017] The method for processing the composite microtexture on the surface of a ductile iron material by laser comprises the following steps.
[0018] (1) Prepare the workpiece [8], the workpiece material is QT900-5, firstly polish the surface with sandpaper to make the surface burr-free and smooth. Ultrasonic cleaning with acetone, ethanol, and water for 1-3 minutes each to make the surface free of oil, particles, and other pollution.
[0019] (2) Fix the fixture [10] on the di...
