摘　　要：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 surface hardness of ferromagnetic material and intensity of Barkhausen Noise has been studied. The results of experiment has shown that intensity of Barkhausen Noise will increase with the decreasing of surface hardness. So surface hardness of ferromagnetic material can be tested nondestructively by using of Barkhausen Noise intensity.
