1. Corrosion of the outer surface of the journal: Spectral analysis revealed that the concentration of iron is abnormal; there are many submicron particles of iron in the iron spectrum; the water is overrun or the acid value is overrun.
2, tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements is abnormal, the iron spectrum presents a number of non-ferrous metal components of sub-micron wear particles, lubricating oil moisture overrun, acid value overrun.
3, fretting wear behind the tile: spectral analysis found that the iron concentration is abnormal; there are many iron components in the iron spectrum sub-micron wear particles; lubricating oil moisture and acid value is abnormal.
4, the external appearance of the journal: there are iron-based cutting abrasive black oxide particles in the iron spectrum; metal appearance has tempering color.
5, tile surface shedding: There are many large-scale fatigue-shedding alloy wear particles and layered abrasive grains found in the iron spectrum.
6, bearing external strain: found in the iron spectrum cutting abrasive; abrasive particles are non-ferrous metals.
7. Bearing burnt tile: There are many large-scale alloy abrasive grains and black metal oxides in the iron spectrum.
