1. Tile corrosion: spectrum analysis found that the concentration of non-ferrous metal element is abnormal;
Iron spectrum appeared a lot of sub-micron wear particles in non-ferrous metal components; moisture
in Lubricating oil & acid value exceeded.
2. The strain on the surface of the shaft neck. iron spectrum in Germany bearing contains iron series cutting grin-ding grain or black oxide particles, and the surface also has heat tint.
3. Corrosions on the surface of shaft neck: Spectral analysis found that iron concentration is abnormal, and
there are a lot of iron elements submicron particles in the iron spectrum, also water in lubricating oil or acid
value exceed.
