磁记忆检测技术(MMT)是基于漏磁检测方法上的一种新兴无损检测(NDT)技术,是迄今为止对金属部件进行早期诊断唯一行之有效的无损检测方法。本文着重介绍了磁记忆检测技术的原理、检测设备及其在实际生产中的应用。
Magnetic memory testing (MMT) is an emerging nondestructive testing (NDT) technique based on magnetic flux leakage testing. It is the only effective nondestructive testing method for the early diagnosis of metal parts. This article focuses on the principle of magnetic memory testing technology, testing equipment and its application in the actual production.
