Surface structures formed on AISI 420 stainless steel by pulsed laser irradiation
Апстракт
The effects of TEA CO2 laser radiation on AISI 420 stainless steel and formed surface structures are studied. The laser energy density of 45.0 J/cm(2) has modified the target surface. Qualitatively, the modifications of AISI 420 steel can be summarized as follows: change of color after action of one laser pulse; central zone of interaction in crater like form and periphery zone of interaction (for more than 10 laser pulses); appearance of grainy features and ablation rate of near 4 rim per laser pulse (action of 400 laser pulses); hydrodynamical effects like resolidified rim and droplets.
