用800 nm，35 fs，4 Hz，0.7 J/cm ~ 2的线偏振激光以不同脉冲数照射不锈钢表面。环境扫描电子显微镜（ESEM/EDS）用于详细的形态，微观结构和组成的研究。用JC-2000 X型界面张力仪测试了辐照后不锈钢表面的润湿性，并与未辐照不锈钢进行了比较。结果表明，在纳米晶表面形成了不同周期的微/纳米条纹。从450 nm（90个脉冲）到500 nm（180个脉冲），周期随脉冲数的增加而增加。这些条纹的取向与激光束偏振方向平行。在这些周期性结构上观察到纳米颗粒。EDS分析表明，激光辐照后，涂层中Cr原子比增加，Fe和Ni原子比降低，这可能是由于富Cr层的存在而提高了涂层的耐蚀性。所制备的结构不经进一步处理就具有疏水性。并对微/纳米周期结构的形成机理进行了探讨。
Stainless steel surface was irradiated by linear polarized laser (800 nm, 35 fs, 4 Hz and 0.7 J/cm2) with different pulse numbers. Environmental scanning electron microscope (ESEM/EDS) was used for detailed morphology, microstructure and composition studies. The wettability of irradiated steel surface was tested by Interface Tensiometer JC-2000X and compared with untreated stainless steel. Results showed that micro/nanostripes with different periods were formed. The period increased with the increasing pulse numbers from 450 nm for 90 pulses to 500 nm for 180 pulses. The orientation of those stripes was parallel with the laser beam polarization. Nanoparticles were observed on those periodic structures. EDS indicated that the atomic ratio of Cr increased and the atomic ratios of Fe and Ni decreased after laser irradiation, which may enhance the corrosion resistance due to the Cr-rich layer. The prepared structure exhibited hydrophobic property without further treatment. The formation mechanism of micro/nanoperiodic structures was also explored.
