The article analyzes sereval methods of monitoring technology of wear debris based on the review of various principles ,features and applications. The study of Ferrography is significant to the monitoring technology of wear debris. The Ferrography is a technique of classifying and counting the wearing grain in the lubricant by the magnetic field. This technique can be used to diagnose the origin of the abnormal wear and the exact facts of the mechanical wear by inspecting the wearing fragment on the ferrography slice. It＇s often used to inspect abnormal wear and to detect the category and degree of the wear. It can provide the basic information for predicting the wearing part＇s life. This makes it possible to obtain more adequate information of the wear debris with ferrogrphy.
