采用纳秒激光器在316L不锈钢表面织构了微孔和微光栅阵列,采用UMT-2摩擦磨损试验机对其摩擦特性进行测试。结果表明,在相同载荷和滑动速度下,光滑表面的磨痕深而且宽,织构化表面的磨痕浅且窄。另外,织构化的表面比光滑表面的摩擦阻力变化稳定;微孔和微光栅阵列越密集,摩擦阻力越小。实验结论:微孔和微光栅能提高不锈钢表面的耐磨性,微孔的减摩效果优于微光栅结构。 Microformatic and micro-grating arrays were fabricated on 316L stainless steel by using nanosecond laser. The tribological properties were tested by UMT-2 friction and wear tester. The results show that the smooth surface has deep and wide wear marks at the same load and sliding speed, and the wear marks on the textured surface are shallow and narrow. In addition, the textured surface has a more stable frictional resistance than the smooth surface; the more dense the micropores and micro-grating arrays, the lower the frictional resistance. Experimental conclusion: Microporous and micro-grating can improve the wear resistance of stainless steel surface, micro-pore anti-friction effect is better than the micro-grating structure.
