Fretting Wear Tester Overview

Main Features:

10 µm to 2.8 mm Stroke
1 to 300 Hz frequency
High frequency piezo Sensors
Electromagnetic Coils

Why Fretting Tests? 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 wear 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 tester for both industry and university research.

Fretting tester series from Rtec Instruments

A Fretting Machine Like No Other

Test the surface damage that occurs between two contacting surfaces. Analyze two-body abrasion, adhesion, and/or fretting fatigue wear.

Down Force Control

Real time down force control to account for contact wear.

Voice Coil

Electromagnetic actuator that imparts linear reciprocating motion. Dependent on the test additional coils can be installed on the tester to double the force range

High Accuracy Position Control

The most accurate and precise displacement control in the market. Up to 1nm resolution and micron level of accuracy. Extremely low noise. High responsiveness for dynamic performance of system.

Environmental Control

Study fretting wear across a wide range of temperature.

Unmatched Waveform Control

Without the friction of rolling or bearing, the magnetic flexure based design provides the control required for the most sensitive of tests. The unique controller adjusts to friction changes to maintain the stroke control in real-time.

Friction Measurement

The fretting tester comes with high frequency piezo sensors to measure real-time friction. Ultra low noise amplifiers aids in detection of minute changes in friction with ease.

Additional In-line Sensors

Sensors such as acoustic emission to detect onset of cracks, and ECR to measure surface resistance changes to gain more insight on the material interface.

Liquid Containers, Sample Holder

Customizable liquid and sample holders for standard and non standard tests.

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 wave form correction controllers. The difference in model lies in the power the coil can impart during the test.
