研究了巴克豪森噪声强度与铁磁材料表面硬度之间的关系.结果表明随材料硬度的降低巴克豪森噪声的强度逐渐升高,因此可以用巴克豪森噪声强度无损测量铁磁材料的表面硬度.
The relationship between the Barkhausen noise intensity and the surface hardness of ferromagnetic materials is studied.The results show that the Barkhausen noise intensity increases with decreasing hardness of the material, so the surface of the ferromagnetic material can be non-destructively measured using Barkhausen noise intensity hardness.
