Tester for Research & Development and Industry
- High speed wear, friction testing
What is fretting?Fretting Actuator Selection
Fretting wear is a tester where surface damage occurs between two contacting surfaces experiencing oscillatory displacement of small amplitude. At the contact point, lubricant/coating is squeezed out, or debris is accumulated that results in metal-to-metal contact. The low amplitude motion does not permit the contact area to be relubricated/debris dislodge, serious local wear occurs. This type of wear causes two-body abrasion, adhesion and/or fretting fatigue wear. Fretting wear when done in a corrosive environment, greatly accelerates wear.

Controller and algorithms
Data showing real time force control and displacements
Proprietary controllers and embedded algorithms to acquire data and i n real time control strokes at high frequency allows the fretting tester to achieve high repeatability and precision.
Automatic Stribeck curve
The fretting Tester can automatically plot friction vs load/velocity curves at different temperature and humidity. This curve helps in comprehensively differentiating different samples.
The tester comes with controlled environmental chambers.
