Research on Surface Morphology and Process Design of Laser Cleaning Automobile Brake Disc
In this study, nine sets of process schemes were designed to utilize nanosecond pulse lasers in conjunction with high-speed galvanometers for the purpose of clearing surface stains from automobile brake discs. Typical experimental studies were carried out on three groups of optimal morphology parameters, the results show that the surface after laser cleaning is bright and smooth, and the minimum surface roughness reaches Ra (1.2 ± 0.3) μm. The thickness of the cleaning layer is about (80 ± 11) μm in the three groups of optimal parameters, and the surface microhardness increased from the original (360 ± 13) HV to (598 ± 26) HV. Despite encountering residual tensile stress post-cleaning, there was a marked enhancement in surface wear resistance, accompanied by a reduction in the friction coefficient from 8.56 to 3.26.
