Laser Focus

Fabrication of friction reducing and anti-wear surface with regular micro/nanostructures is a hotspot of surface engineering studies nowadays. We present a simple and easily-controlled method for fabricating stainless steel-based nanostructures surface. First, by strictly controlling the number of femtosecond laser pulses, two kinds of nanostructures are fabricated. Then, forming mechanisms of nanodots and ripple structure are analyzed. Lastly, we obtained uniform large-area nanodots and ripple structures by adjusting the repetition rate of laser focus accurately. Therefore, this technique will provide a good method to investigate the tribological properties of controllable nanotexture surface.

Pyramid Structure

The formation of layered ripples covered pyramid structure is reported on 316L stainless steel surface with femtosecond laser pulses in this paper. These unique structures form though a combination of preferential ablation of flat regions around the pyramids and extension of layered ripples created during the ablation process. The cause of the formation about these structure is investigated using multi-means and the results show that these structures are derived from an inhomogeneous distribution of laser fluence, which is caused through a combination of the redeposition of nanoparticles and the local oxidation as well as the geometric factors.
