Damages as a Result
18
„80% of particles and water are
the cause of malfunctions and
damage in hydraulic systems,
gearboxes and rolling bearings“
Consequences:
• Hydrolyse – Rapid aging
and degradation of additives
• Promotion of corrosion
• Worse lubrication

• Adsorption is based on attractions (Van der Waals forces)
• Van der Waals forces are solvable again → Desorption
