1, tile surface corrosion: spectrum analysis found that non-ferrous metal element concentration anomaly; Iron spectrum appeared a lot of non-ferrous metal components in sub-micron wear particles; Lubricating oil excess moisture, acid value exceeds bid. 2, shaft neck surface corrosion: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum of submicron particles, water or high acid value oil paint. 3, a shaft neck surface strain: iron spectrum have iron series cutting grinding grain or black oxide particles, metal surface heat tint. 4, tile back micro wear: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum wear submicron particles, lubricating oil moisture and acid value anomalies. 5, a bearing surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal. 6, tile surface spalling, finds many large size iron spectrum fatigue spalling alloy wear particles, the layered grits. 7, bearing tile burning: there are more iron spectrum by means of large size, alloy and black metal oxides.
