Experimental investigation on nanoprocessing of stainless steel surface

摘要

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.
