Fretting wear is a test where surface damage occurs between two contacting surfaces experiencing oscillatory displacement of small amplitude. At the contact point, lubricant/coating is squeezed out or the low amplitude motion does not permit the contact area to be re lubricated/ debris dislodge resulting in serious local wear occurs. This type of wear causes two-body abrasion, adhesion and/or fretting fatigue wear.

Difference in Voice Coil Power For Friction Force
All Rtec Fretting test machines are constructed on flexure based designs. The motion is imparted using electromagnetic actuators with real time stroke and wave form correction controllers. The difference in model lies in the power the coil can impart during the test
●FFT-2 5000N Down Force (Floor Standing, Dual High Power Coil)
●FFT-1 3000N Down Force (Floor Standing, Single High Power Coil)
●FFT-M2 1000N Down Force (Bench Top, Dual Medium Power Coil)
●FFT-M1 300N Down Force (Bench Top, Single Medium Power Coil)
