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.

The greases' fretting behavior at small vibration amplitudes (50-200 µm) showed no significant improvements in friction, contact resistance or wear compared to

In this study, the fretting wear behavior of Ti-6Al-4V alloy was investigated by changing the load and displacement under a high frequency (100 Hz). Fretting & Wear Fretting refers to small oscillatory displacements, of machine components for example, that cause surface damage such as wear, fatigue, corrosion etc. Actually, fretting wear is defined as “a special wear process that occurs at the contact area between two materials under load while subjected to minute relative motion by vibration or some other force”. 2013-12-27 · Fretting is gradual wear by means of rubbing or gnawing action between two surfaces. Fretting corrosion is a combined action of fretting as well as corrosion, which involves corrosion at points where two metal surfaces make contact by means of a rubbing action. Fretting wear is the wear phenomenon occurring between two surfaces having oscillatory relative motion of small amplitude. Besides being a form of wear, fretting can have a deleterious effect on the fatigue life of parts which are subjected to it. fretting wear rate of the contact.

Research has shown that over 60% of the electric problems in cars are directly related to fretting wear. Our ADVT Lab designed and built equipment to test lubricants to their ultimate fretting Fretting Corrosion (and fretting motion, the driving force behind fretting corrosion). How is this different from normal plain old wear? The big difference is that fretting is a micro-motion issue typically less than 0.005” of movement. Just about any material that oxidizes is in danger of fretting corrosion under the right conditions.

Fretting occurs at fitting surface and also at contact area between raceway ring and rolling elements. Fretting corrosion is another term used to describe the reddish brown or black worn particles.

Fretting wear often involves several complex wear mechanisms taking place at the contact surface, including two-body abrasion, adhesion and/or fretting fatigue wear. In order to understand the fretting wear mechanism and select the best material for fretting wear protection, reliable and quantitative fretting wear evaluation is needed.
