Fretting is damage caused by low amplitude vibration and/or small oscillations between two surfaces in contact with each other. This damage often goes unnoticed for a long time. Over long periods, particularly at high temperatures or in corrosive environments, this friction can lead to fatigue cracking and loss of component functionality.


Oerlikon Metco offers coating solutions that provide excellent anti-fretting properties. For Solutions, thermal sprayed copper-nickel-indium prevents fretting on the roots of gas turbine blades against disk slots.
