High Frequency Fretting Wear Test System

The Fretting is one of the major problems especially in Aircraft industry. Fretting arises when two materials are in contact under pressure and small-scale relative motion occurs between them. The damage from fretting can be caused either by fatigue of one or both contacting materials or from wear, in which enough of the contacting material is worn away.

The purpose of fretting fatigue test is to simulate the conditions with some simplifications to analyze the wear of coating on the specimen to prevent fretting damage. A servo hydraulic fatigue testing machine with specially designed fretting pads and a fretting fixture is designed to do the test.

Features

  • Double-acting servo-hydraulic actuator with force capacity up to ±10 kN
  • 150 mm (6 in) of usable stroke
  • High-stiffness, precision-aligned, self-reacting load frame with twin columns and actuator in top crosshead
