摘要
采用波长为1064 nm的光纤激光器对Q345钢表面锈层进行激光清洗,研究了激光扫描速度对清洗质量的影响。结果表明:当扫描速度小于1000 mm·s -1时,激光对基体的损伤较大;当扫描速度达到5000 mm·s -1时,部分锈蚀仍残留于材料表面;当扫描速度为3000 mm·s -1时,清洗效果较好且基体不会受到损伤。随着扫描速度从1000 mm·s -1增加到6000 mm·s -1,清洗后Q345钢表面的铁含量呈现先增加后降低的趋势,而氧含量则是先降低再升高。当扫描速度为3000 mm·s -1时,Q345钢表面清洗后铁元素的质量分数达到了峰值,约为90%,氧元素的质量分数则达到谷值,约为7%;铁与氧的化合物较少,且钢的表面粗糙度亦较低,Ra≈6.9 μm。通过调节扫描速度可以获得较好的激光清洗效果;激光清洗后,Q345钢表面的电化学腐蚀性能有所提高。
Abstract
A fiber laser with a wavelength of 1064 nm was used for laser cleaning of the rusted layer on Q345 steel surface, and the effect of laser scanning speed on the cleaning quality was studied. The results show that when the scanning speed is smaller than 1000 mm·s -1, the laser significantly damages the substrate; when the scanning speed reaches 5000 mm·s -1, some rust remains on the material''s surface; when the scanning speed is 3000 mm·s -1, the cleaning effect is better and the substrate will not be damaged. As the speed increases from 1000 mm·s -1 to 6000 mm·s -1, the Fe content on the Q345 steel surface after cleaning shows a tendency of increasing firstly and then decreasing, while the O content decreases firstly and then increases. When the scanning speed is 3000 mm·s -1, the Fe element content on the Q345 steel surface reaches a peak of about 90%, the O element content reaches a valley value of about 7%, the compounds of Fe and O are also less and the surface roughness (Ra≈6.9 μm) of the steel is also low. Good laser cleaning effect can be obtained by adjusting the scanning speed appropriately. After laser cleaning, the electrochemical corrosion performance of Q345 steel surface can be enhanced.
