Fretting is the result of damage from low amplitude vibration and/or small oscillations between two surfaces in contact with one another. Often, this damage can go unnoticed for a long time. Over longer periods, this friction can lead to fatigue cracking and loss of component functionality, particularly at high temperatures or in corrosive environments. Sulzer Metco offers coating solutions that exhibit excellent properties for anti-fretting applications, such as thermal sprayed copper-nickel-indium for the roots of gas turbine blades.
