For example, Li Fretting decreases fatigue strength of materials operating under cycling stress. This can result in fretting fatigue, whereby fatigue cracks can initiate in the fretting zone. Afterwards, the crack propagates into the material. Lap joints, common on airframe surfaces, are a prime location for fretting corrosion. Fretting wear is a destructive phenomenon that can seriously affect the reliability and the durability of vibrating components, leading to premature catastrophic failures fl, 2], It can be found in many accessories and/or components, such as bearings, gears, and clutches [3]. Fretting is a poorly understood form of fatigue caused by minute oscillating motions between materials in rubbing contact.

fretting process, when they form interfaces under normal service [9, 10]. Theories such as the stick–slip effect [11, 12] can help in the understanding of the fretting phenomena. However, the fretting process for Al, Si, and diamond, until recently, has not been fully understood by the characteristic interface configuration. For example, Li

This is a high-quality dovetail-style saw, perfect for cutting fret slots for standard fret wires that fit in a .023" slot. The blade has a .020" kerf and is 8" long with a steel reinforced ridge along the top - much like the more expensive fretting saws sold elsewhere.
