摘要: Abstract. Laser scribing is widely used to reduce core loss of grain-oriented silicon steel recently. The effects laser on surface coating and magnetic properties were investigated in this paper. effect stress annealing treatment product has been analyzed. It was found that as power increased, the reduced damage exacerbated. Reducing line spacing a certain width can achieve low loss. domain refined will increase after at temperature.
