Fretting Tester
FFT Series - Rtec Instruments (Rtec)
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.
