摘要
通过实验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 ,因此可以利用巴克豪森噪声强度对材料的表面硬度进行无损测量。
The relationship between the surface hardness of ferromagnetic material and the intensity of Barkhausen noise was studied. Experimental result showed that the intensity of Barkhausen noise increased with the decreasing of surface hardness. It was concluded that the surface hardness of ferromagnetic material could be measured by Barkhausen noise intensity.
