介绍了从事无损检验技术工作中对剩磁法探伤(即磁粉悬浮液法)零磁漏检的试验研究.研究表明:解决剩磁法探伤的零磁漏检问题,可以进一步扩大其应用,消除质量隐患,可靠地检查出钢铁零件表面或近表面最危险的缺陷——裂纹.
This paper introduces the experimental study on zero magnetic flux leakage of the residual magnetism method in the work of nondestructive testing technology.The research shows that to solve the zero magnetic flux leakage detection problem of the residual magnetism method can further expand its application and eliminate Hidden quality, reliable detection of the surface of steel parts or near the surface of the most dangerous defects - cracks.
