Effects of pulsed laser ablation on magnetic losses of GO electrical steels along various excitation directions
Abstract
Surface laser treatment is an effective way of improving magnetic properties of Grain-Oriented Electrical Steels (GOES). However, these enhancements generally only concern their easy magnetization axis aligned with their Rolling Direction (RD). In this work, the effects of an ablation laser process (implemented with advanced UltraShort Pulse Lasers (USPL)) on the magnetic properties of GOES are investigated for various excitation configurations. Both conventional and non-conventional laser patterns are also used and compared. Experimental results show that the ablation process can improve performances of GOES not only along the RD but also along other excitation directions providing an adaptation of laser patterns when the excitation direction changes.
