EXPERIMENTAL DETERMINATION OF THE EFFECT OF DENSITY OF POWER LASER λ = 1064 nm ON THE EFFECTIVENESS OF LASER STEEL ONE PULSE TEXTURING 41Cr4
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2012, Vol 59, Issue 256
Abstract
This study attempts to determine the effect of the experimental efficiency of the one pulse laser texturing of the alloy41Cr4. The study used modern ytterbium fiber laser pulse and solid galvo head with wavelength lambda = 1064 nm and nanosecond pulse duration. The geometrical analysis produced microkraters performe dusing an optical microscope with fiber-optic image transmission. One study found that an increase in the radiation power density q = 0,6 MW/cm2 significantly affect the efficiency (depth) of ablative laser texturing. After crossing the power density is a significant reduction in the efficiency of laser ablation process. This is probably connected with the phenomenon of plasma shielding generated in the laser pulse.
