Ferrographic analysis is becoming the most effective oil analysis method for monitoring machine wear condition and making the maintenance strategy.A large number of debris images accumulated during the machine oil monitoring were classified based on different characteristics of the wear particles in industrial enterprises in recent years, and relevant lubrication management maintenance strategies were proposed based on the forming mechanism and reasons of the deferent debris.Application shows that ferrographic analysis plays an important role in monitoring machine wear condition,distinguishing lubrication and wear mechanism, and promoting the enterprise lubrication management activities.
