1, tile surface corrosion: spectral analysis found abnormal concentrations of non-ferrous metal elements; iron spectrum, there have been a number of sub-micron wear particles of non-ferrous metals; lubricants excessive moisture, acid value exceeded.
2, surface corrosion journal: spectral analysis found abnormal concentrations of iron, iron spectrum, there are a number of sub-micron particles of iron components, lubricants excessive moisture or acid value exceeded.
3, the journal surface strain: iron spectrum in the presence of an iron-based cutting abrasive temper color or black oxide particles, the metal surface.
4, tile back fretting: spectral analysis found abnormal concentrations of iron, iron spectrum, there are many iron content submicron wear particles, water and lubricating oil acid value exception.
5, the bearing surface strain: iron spectrum found in cutting abrasive, abrasive component of non-ferrous metals.
6, peeling tile: iron spectrum found in many large fatigue spalling alloy wear particles, layered abrasive grains.
7, the bearing bush-burning: iron alloy grains spectrum have more large-size and black metal oxides.
