| 表面润湿性是表面技术的研究热点。 为研究不同加工环境中激光制备微织构对 304 不锈钢表面润湿性的影响,采用光纤激光打标机,在空气、无水乙醇环境中采用一步法制备了微织构表面,从织构形貌、织构表面化学成分分析加工环境及激光参数对 304 不锈钢表面润湿性的调控机理。 结果表明,无织构 304 不锈钢表面接触角为 56. 89°,表现出了亲水特性;空气环境中制备的织构为微米尺度的沟槽织构,与无织构 304 不锈钢表面相比 O 原子明显增多,其表面接触角为 10. 61°,表现出了高亲水特性;试验所选参数范围内,无水乙醇环境中制备的织构为不规则的微纳织构,与无织构 304 不锈钢表面相比新增了大量 C 原子,其表面接触角为 66. 14° ~ 117. 83°,表现出了疏水特性;亲/ 疏水表面可以应用在微量液体的定向输运。 影响 304 不锈钢表面润湿性的因素主要有:织构形貌,表面化学成分。 该研究为 304 不锈钢表面润湿性调控提供了参考。 |

| Abstract: |
| Surface wettability is a research hotspot of surface technology. In order to study the influence of laser micro texture on the wettability of 304 stainless steel surface in different processing environments, the micro textured surface is prepared by one-step method in air and absolute ethanol environment with fiber laser marking machine. The control mechanism of processing environment and laser parameters on the wettability of 304 stainless steel surface was analyzed from texture morphology and chemical composition of texture surface. The results show that the surface contact angle of non-textured 304 stainless steel is 56. 89 ° which shows hydrophilic property. The texture prepared in air environment is micro scale groove texture, and the number of O atoms is significantly increased compared with the non-texture 304 stainless steel surface, and the surface contact angle is 10. 61 ° which shows high hydrophilic property. In the range of experimental parameters, the texture prepared in absolute ethanol environment is irregular micro-nano texture. Compared with the non texture 304 stainless steel surface, a large number of C atoms are added, and the surface contact angle is 66. 14 ° to 117. 83 ° which shows hydrophobic property. The hydrophilic / hydrophobic surface can be applied to the directional transport of micro liquid. The main factors affecting the wettability of 304 stainless steel are texture morphology and chemical composition of the surface. This study provides a reference for the surface wettability control of 304 stainless steel. |
