Surface strain: iron spectrum found cutting abrasive, abrasive ingredients for non-ferrous metal. 3. Tile back micro wear: spectrum analysis found that iron concentration is unusual, there are a lot of iron in iron spectrum component wear submicron particles, lubricating oil moisture and acid value anomalies.
