This research introduces a method of making magnetic glass by welding magnetic powder with a femtosecond laser. The study highlights the impact of high repetition rate on welding quality, and proposes an efficient, accurate, and environmentally friendly approach for fabricating magnetic glass for various applications.
This research provides a method for making magnetic glass by using a femtosecond laser to weld magnetic powder into a welding line. In this paper, considering that the high repetition rate is regarded as an important parameter affecting the welding quality, the change laws of the bonding strength and saturation magnetization of magnetic glass after welding with the high repetition rate were studied. This paper presents a promising method to fabricate magnetic glass for different utilizations in an efficient, accurate and environmentally friendly way.
