Fretting Wear Tester

Main Features:

  • 10 µm to 2.8 mm Stroke
  • 1 to 300 Hz frequency
  • High frequency piezo Sensors
  • Electromagnetic Coils
Why Fretting test?  Small oscillatory motion between contacting surfaces causes accumulation of wear debris in the contact zone. Thus greatly speeding up the wear process. Several applications such as aerospace, automotive, machinery, displays, and medical devices commonly observe fretting wear.

Rtec Fretting Solution – The state-of-the-art fretting testers provide unequaled specifications of stroke and frequency in the industry. Controlled stroke from 10 microns and frequency up to 300 Hz frequency makes it an ideal fretting wear tester for both industry and university research.

The difference in Voice Coil Power For Friction Force
All Rtec Fretting testers are constructed on flexure-based designs. The motion is imparted using electromagnetic actuators with real-time stroke and waveform correction controllers. The difference in model lies in the power the coil can impart during the test.

FFT-M Series
Up to 500 N Down Force (Bench Top, Single or Dual Medium Power Coil)

3000 N Down Force (Floor Standing, Single High Power Coil)
5000 N Down Force (Floor Standing, Dual High Power Coil)

Data and Analysis
FFT series fretting wear test instruments optimize friction, wear, fretting fatigue tests at small amplitude and high frequency. 

Fretting Loops
Rigid design with accurate real-time friction force allows the measure of fretting loops at different temperatures and loads.
