摘要
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。
Two kinds of micro-hole and micro-gating on the surfaces of 316L stainless steel were textured by nanosecond-laser, and their frictional behaviors were investigated by the UMT-2 friction and wear instrument. The results show that the frictional resistance of the texture surfaces is more stable than smooth surface, and have the role of stabilizing fiictional resistance. As friction time prolong, the frictional resistance of the smooth surface increase sharply, while the fiictional resistance of the grating structure and hole structure remains unchanged. The more intensive the hole structure and grating structure, the smaller the frictional resistance. The experimental conclusions： the micro-hole and micro-grating can improve the wear-resisting property, and the antifriction performance of the hole structure is superior to the grating structure.
