Nondestructive testing method for nonferromagnetic material

Номер: CN0102012397A
Автор: Ju Wei, Ke Liming, Meng Yongyue, Yu Runqiao
Принадлежит:

The invention relates to a nondestructive testing method for a nonferromagnetic material. The method comprises the following steps of: arranging the nonferromagnetic material in a uniform geomagnetic field; allowing geomagnetic field lines to uniformly pass through a nonferromagnetic material body, wherein the nonferromagnetic material causes the intensity attenuation of the geomagnetic field due to the presence of the magnetoresistive characteristic of the nonferromagnetic material; and processing and inspecting a data value. The invention has the advantages that: the method does not need any coupling agent and manual magnetization, has detection depth which is not limited by material thickness, compact equipment, a simple detection process, a machine-controlled detection process and high repeatability and is independent of the technical level and working attitude of detection personnel.
