Erosion

• Fine scoring in the direction of the oil flow
• Roughening and fissures of the sliding layer

Erosion is a form of abrasive material removal, caused by the flow forces of the oil. This effect is reinforced by the smallest particles in the oil, such as carbon deposits or deposits from abrasion. Erosion is also often the result of cavitation, as here particles from the material are broken off and enter into the lubrication system.
Erosion attacks the material surface and activates it chemically, accelerating the initial corrosion. The integrity of the material is also influenced negatively as the fissures on the surface can cause cracks. Damage caused by fatigue is the result.

Due to the use of thin oils, erosion is occurring more and more frequently.

• High speeds and low bearing clearance
• Use of incorrect engine oils with, for example, the incorrect additives or without additives at all
• Smallest particles in the oil flow: particles may come from different areas of the engine and may have been caused by incomplete combustion or cavitation, for example

• Keep the temperature of the oil low through sufficient cooling
• Always replace the oil filter and oil according to the manufacturer‘s specifications: ensure that the inspection intervals are complied with and only oil and oil filters to the right standard are used
