Fretting resistance
WebFretting wear is a special wear process that occurs at the contact area between two materials under load and subject to minute relative motion by vibration or some other force. Fretting wear is similar to adhesive wear in that microwelding occurs on mating surfaces. WebFeb 9, 2024 · The effects of the two forms PTFE particles on the fretting wear resistance and mechanical properties of the composites were studied. Especially, the fretting wear behaviors of the composites with GCr15 ordinary steel and M30MN 2 marine steel balls as friction pairs were compared.

WebIt occurs frequently whenever metal surfaces are in contact, sliding against each other, especially with poor lubrication. It often occurs in high-load, low-speed applications, although it also can occur in high-speed applications with very little load. WebApr 11, 2024 · The high fretting resistance of anodized TiNbSn was attributed to the hard, thick, and strongly-adhered rutile TiO 2 layer, which was formed by spark discharge owing to dielectric breakdown. In conclusion, the anodic oxide layer on TiNbSn offers superior fretting tribocorrosion resistance owing to rutile TiO 2. Thus, anodized TiNbSn is …
